View Full Version : My reality check with the Phil Jones Double Four.

For the last month or more I've been rehearsing diligently with The CC Strummers for our show this morning at the Fiesta La Balloņa in Culver City, California on my custom bass uke and Phil Jones Bass Double Four 70 watt amp. For a short time I also used a Sony wireless system, but at the last rehearsal, the amp clipped and shut down two times and wouldn't come back on for at least five minutes. I pulled the wireless system and went back to a standard 1/4" cable, which worked fine in the room with 30 or so players.

This morning we setup and did a quick sound check, my PJBD4 with standard cable did fine, 8-9 on the amp and 7-8 on my bass preamp. A few minutes later we started our 1/2 hour 10 song set. I moved my bass preamp volume to about 9 and two notes in, the amp clipped and shut down. It wouldn't come back for two songs. CRAP! (I used much stronger expletives at the time.)

Not only that, outside under a large open sided tent with 45 players, an audience of about 150 and our leader Cali Rose mic'ed through the PA system, my 70 watt amp just couldn't keep up. The other bass player using a Kala U-Bass and Pig Nose Hog told me the same thing after the show. (W've not been allowed to plug into the PA, so I can't plan on that in the future).

So after stuffing my frustrated face with fried calamari and BBQ ribs, I went out to find a better portable, 200 watt minimum battery amp setup. First I stopped at Guitar Center WLA, but they didn't have anything that was small with enough power.

Then I went to Sam Ash Hollywood and came to the conclusion that a battery system would not be possible with 200 watts or more (a car battery and inverter are not convenient). The sales guy showed me the smallest and lightest setup with enough power; a new Aguilar Tone Hammer 350 head for $455, and a floor model discontinued Fender Rumble 112 speaker box, 12", 500 watt for $290, both together have continuous 280 watts and peak 500 for $825 out the door.

I tested it out at the store and it sounded good to me, next I'll take it to rehearsal tomorrow and see how well in works there. It has a 30 day return policy.

So as much as I like the Double Four, the reality is that it's only good for small spaces that are not overpowered by a big sound system.

Any reason you're not allowed in the PA? Some of the stories I'm hearing about uke groups from you and katysax make me shake my head. I knew some people in this area in a "folk society" and it sounds similar. I guess I always just figure that whatever makes things work and sound best should happen.

That amp and cab you bought will be really nice though,aguilar makes excellent amps. I could have bought their 200 watt tube head about 15 years ago for $700, I kick myself for missing that!

Cali thought that it would be to overpowering, so I figure I'm just going to be ready next time. I sure hope the A&F combination will do the job. Now I have to pick up a 25-50 foot extension cord, not leave that up to the venue or sound people.

Unfortunately, the Rumble 112 isn't going to keep up either. No matter how much power your head has it is going to be limited by the volume of the cabinets. You are going to need at a minimum either 2 2x10s or one 4x10 to keep up in the situation you describe. When you are outside the open air really eats up the sound. I have a Kustom PA system that I got for $100 from Guitar Center. The other thing that I do is run amps in parallel. I have a powerful head and a 1x10 cab, and it is nowhere near enough for the kind of outdoor situation you were in. Phil Jones sells the PB300 powered extension cab that is about $100 more than what you just spent and it would give more power than what you bought (I don't own one). But I'd be more inclined to go with my own portable PA setup. I don't want to own a 4x10 or even two 2x10 cabs or lug them around so I prefer a PA. It's not exactly primo sound, but you could run two of the Kustom PA systems in parallel and it would be good enough for an outdoor festival like that. You would still use your Double Four as a monitor and as a DI for the PA system. I use a Lehle Split II to divide the signal between two amps. I suggest you test the stuff you bought outdoors because I'm sure it isn't loud enough. If you agree you can return it. Actually you can borrow PA stuff from me if you need it for a festival like that. However, you should just convince Cali to let you use the PA. It's not overwhelming if you control it. An outdoor space really swallows the bass sound you need a lot of power.

I've had pretty good luck with the Bass Cub in a pretty large hall, but I've also tried amps where you just can't hear it. And it gets lost fast when outdoors. You really need a lot of power if you don't have PA reinforcement.

The Double Four is plenty adequate to be heard in a decent sized restaurant room with 25-30 ukes so long as they are not mic'd but it needs the room to contain the sound.

Oh boy, not so good to hear, though the Fender 112 cabinet is 500 watts with a 12" speaker. I first looked at PA systems, but they were so big, and I was swayed away by the salesman that a PA would not have a deep enough tone for a bass. I really want something that's small enough to fit the foldaway cart I use and still have enough power. I figure I'll try the system when we play at the Los Angeles International Uke Festival on Sept. 26th, which still gives me time to return it.

What's the reason you can't go through the PA? Setting up extra PA systems, buying hundreds of watts of bass amp to be heard alongside a PA, etc, makes no sense. Plus, to generate enough volume to be heard by people in the audience alongside a PA you'll be turned up at a point at which I can guarantee everyone onstage will complain about volume.

I play in a few wedding bands, as well as bar gigs, etc around here, and the only time I'm not in the PA is if it is such a small situation that there's no way it can work. Currently I use a TC bh200 and a 1x10 cab I made and I've never had the head past halfway. For me that was way too loud but that's where others wanted it! On Saturday I got to the gig and realized my head (the amp, but my head would be forgotten if it wasn't attached!) was still at my house. I was with the bandleader helping with PA and so I just grabbed one of the extra powered monitors in the van (extra, as in not very good, usually a distorted mess when vocals are going through it) and off we went. It sounded great onstage, and i was going through the DI I always use anyway, so no worries about being too loud. Of course, I then found out that when the father of the bride said he wanted no danceable music until after dinner that meant NO volume- the first time we've ever been told that the girl from Ipanema was too loud and raucous, even with the drummer playing with his hands...sigh.

Anyway, curious situation you have with that, I hope you find a solution that works for you.

Another +1 to katysax's comments about playing outdoors with no PA support. I did a gig last month outdoors, and even with support, my big amp (Phil Jones Bass D-600 head and two 4B cabinets) still was quiet to my ears.

Since that Fender cabinet is only 8ohm, you're only getting about 175w out of that amp head, so I think you may sadly be disappointed again. If you added a second 1x12, you might be able to be heard (and you'd be getting the full 350w from the head, although the speakers are ultimately more important) and still be small enough to be put on your cart for loading in/out.

Our leader specifically said that we should not go through the PA, for some reason she thinks that's a problem with the bass, I didn't want to argue with her, but when we finished, I told her that we really needed to be on the PA. She said in this case maybe it would have been OK, but then said the next gig we would not be able to, again, not sure why. I've had a certain amount of live show experience in the past and have used a PA (before I started playing bass). Today the three of us are going to sit down and discuss it.

Jon Moody
08-31-2015, 04:23 AM
Do you have a dedicated soundperson, or someone that hows how to properly use a channel mixer for sound support (and not just someone who can turn things up when they're quiet)? Maybe the leader isn't very knowledgeable in sound reinforcement, and just needs someone there to show/prove how easy it really is with a bit of knowledge.

Perhaps the answer is to get a small mixer to put everything into before the PA. Worried about "overpowering" bass? OK, just turn that little knob down.

I second that...

We don't have a dedicated sound person, we rely on the system that's being used at the venue. The leader has a great deal of live experience, hopefully our discussion later will clarify everything. We will not be carrying our own PA or mixer for sure, either we use an existing PA, or we use our own amplifiers.

I'm getting so much conflicting feedback. I posted this on Talk Bass as well, some say the Aquila Fender will work, some say they use a 30 watt system, but with a big speaker box, others say it's not the power, but the quality of the sound, etc. I bought this system after a good deal of discussion and playing it. It fits in my cart and has power. The only thing I can do at this point is try this setup myself at the uke festival, if it works, great, if not, I'll either have to try other configurations so I know first hand (but can't be physically bigger than this one), or insist on patching into the PA.

I just read that thread over on TB.

Did you use the battery power the entire time for the gig?

If so, at any point did you have the chance to plug the Double Four in to an outlet? Maybe the battery was the issue with the cutting out?

I feel your pain in needing a small, portable bass rig. Many years ago I had a Fiero, and needed a rig that I could transport in it. My old Ric would barely fit in the trunk (sans case) and there obviously wasn't enough room in the passenger seat for my 8x12 Ampeg cabinet and head. After much auditioning and searching, I got what I feel is the perfect small portable rig that actually fit in the little car - an Ampeg Portaflex 15T. It has enough power for most smaller venues as well as a balanced line out for going into the PA at larger clubs, the flip-top design stows the amplifier safely and securely for transport, it has detachable casters, and also serves as a case for transporting effects pedals and cabling. Most importantly to me, it has that great Ampeg sound. That poor thing has gigged with me all across the southeast for about 20 years and other than a few cracked solder joints has been as reliable and sturdy as an anvil.

The newer Portaflex rigs have more power than mine (which is only 100 watts) and IMHO sound a bit better due to the increased headroom. You may want to audition one.

The battery was fine all the way through, it was the D4 amp that clipped and shut down. The difficulty was that it stayed off for more than 5 minutes, so I was out for the first two songs. But since the power I'm now going for cannot realistically use a battery, A/C will be it. I'll use the D4 for rehearsal and small gigs.

Right, but did you have a chance to A/B the Double Four at the gig with the battery and the A/C. A lot of the TB folk seem to think - myself included - that the battery just didn't have the power to give you the clean sound, which is why the Double Four clipped and then shut down.

That doesn't fix the volume issue, but if the battery is limiting the functionality of the PJB, that's another issue that needs to be addressed since you're the only person I've talked with that's had that type of issue with the amp (cutting out).

kohanmike
08-31-2015, 06:17 AM
I guess that's a possibility that I have to try, though the battery is rated at 23,000 milli amps. Once I turned down the volume enough, the D4 did not shut down, but was too low for the gig.

It does have enough power.* All they had to do was take a line out or mic up your amp and mix it on their end. Your bass amp should not have to compete with a PA system. The problem is that the group doesn't understand bass or how to mix.** If they think it's too loud, then they just need to drop the level a bit. This is just user error on their part. I feel your pain.

*The unit could be defective, of course, if it's not operating up to specs.
**If they don't have a mixer or understand how to use one, perhaps that's a job you could volunteer for. I just got my community center to get a simple mixer and they use it for movie night and board meetings. Very handy. http://www.sweetwater.com/store/detail/MG10c?adpos=1o1&creative=55674776881&device=c&matchtype=&network=g&gclid=Cj0KEQjw9o-vBRCO0OLi2PfPkI8BEiQA8pdF4GyrVQFn76g24SRMJ0hBMIWkP naWhvE9BS_RYYFGdrYaArRb8P8HAQ

08-31-2015, 08:47 AM
I just tested and the cutout is because of the battery, when I clip with the battery, the amp shuts off and will not come back for 5 minutes, but when I immediately connect the a/c, the amp comes right back. I can clip the amp constantly with a/c and it stays on.

I also just talked to Steve at Phil Jones and he confirms that the D4 is not at all appropriate for the gig I had. He says that a speaker with a good amount travel is necessary and the Fender should work just fine. I'm also going to trade in the Aguilar for a GK MB500 to get more headroom with the 8 ohm speaker.

I hope your PA discussion goes well. You should not have to be bringing giant amps to a ukulele gig. Your new rig will be fine if you're still not allowed to be in the PA since the leader does not seem to care about having the sound properly balanced or does not understand that it can be.

The other thing is that bass does not need to kill people and make their chest rattle all of the time, as a soundman I can tell you that when I see a giant bass rig that is then cranked up really loud I know I'm going to have a heck of a time mixing. In certain styles the bass is meant to be less impactful but just as important, such as jazz, folk, classical, etc. If a player is too loud though, You can only talk to them about it so much before they just get angry if they are not inclined to address it on the first request. Usually in that case I'll quietly approach the leader later and discuss the situation. In the end, if no one wants to change it then it is what it is. Likewise, there are many times in my bass gigs where someone else is doing sound and I may get comments that the bass is not loud enough in the mix. My response? The leader is doing sound and if that's how he wants it then that's how he wants it. I'm there to play bass and not to do sound, so I just play and if no one can hear my "brilliance" then that's just how it is.

I'm probably not coming across correctly on the internet, I do care about my sound and my playing, but I've also come to accept that some things are out of my control and I'm not going to spend tons of money just because the person I'm playing with doesn't have the proper equipment to do their job, if that's the situation. In the past year, that particular leader has made some major upgrades to the sound system which has now improved the situation a lot.

Bottom line is if your leader still doesn't understand after you discuss, I wouldn't try to buy my way into making any sense, it may just mean you accept it for what it is. My "disposable" income also gets used towards kids' sports, etc and we're at different places in life where my gigs are fun but the income is necessary and I have to remember that my gigs are not there to break even by continually buying new equipment. I love gear as much as anyone else, believed me!

That's me though, and I've been known to be wrong a time or twenty... Just ask my wife, she'll gladly tell you!

I brought the new rig to rehearsal in a large room yesterday and it worked perfectly, it was on 3. It's not a big system, the speaker box is about 20 x 14 x 17 about 24 lbs. and the GK head is very compact compared to the Aguilar. It all fits in my regular size old lady shopping cart.

When we finished the show on Sunday, I asked a couple of the members of the group who were sitting at the front of the stage if they could here me, I was on stage right third row of four, they said no, so I knew I needed a better rig. I'm looking forward to testing it at the Sept. 26 at the Los Angeles International Ukulele Festival, they will not have a PA system at all.

I made a major change today. One of the people on the Talk Bass forum mentioned that he has a Carvin MB15 microbass combo amp (all in one, 15" speaker, 200 watts, $402 total). When I bought the GK & Fender 12" for $820, it was the only small size in the store, and with my knee-jerk reaction to the gig problem, I bought it since none of their 15" were small or light enough.

I did a little research and the Carvin MB15 will fit my cart, so I called Carvin this morning, boy am I glad I did. I explained my situation to Adam and he told me that Carvin makes the MB15 to order and that they could actually put in a lighter weight neodymium higher powered 15" 4 ohm speaker for $70 more, add an extra handle as well, and they have a 10% off sale, so $493.56 out the door, ready in two weeks, $308 less than I spent, wow!

Being that it's my birthday today, I jumped on it. I'm returning the GK and Fender today.

The on going saga; Carvin didn't have a 4 ohm neo, only an 8 ohm, it's 5 pounds lighter than the standard so I went with it, making the amp 200 watts rather than 250. Now I just hope they have it to me before the 26th for my next outdoor gig.

Honestly, it's probably better that you went with the 8ohm version instead. You would've never heard a difference between the 200w and 250w, because you're still only using one 15" speaker. However with the 8ohm speaker in there, should you ever need the option, you can buy the 115MBE extension cabinet to utilize the 250w but more importantly have 2 15" speakers, which will make a much larger difference than the 50w would.

Thanks OBM, that's exactly what both Carvin and my younger brother told me (he's a self taught sound engineer who used to manufacture speakers). I really doubt that I'll ever want to use a second speaker, and hope this 15" compact amp will do what I need, we'll see on the 26th.

Im an experienced bass player and I came to a point that I just accepted that as a bass player I need to haul around a lot of heavy stuff. It's not just watts that count, it's speaker surface as well. I blast 600 watts into two cabinets and that always does the trick. With my uke band I use an ampeg 115 combo which is about 100 watts. I don't understand why you shouldn't be able to go through the pa. As long as there's a di between it it should be the way to go most of the time. In large venues I use my rig as my onstage monitor and use the di out on my top to go into the pa. Or I use my Aguilar tone hammer pre-amp di.
Good luck with finding the right solution!

In this day and age, heavy is not needed anymore. Guys like Carvin, Aguilar, Gallien-Krueger, Acme, etc.. are all taking the time to build cabinets that accurately reproduce the sound and lower frequencies but be smaller and more lightweight than the old Ampeg fridges of old.

I have been playing bass through a direct box and into the PA more often than not these days. While I can't monkey with my tone as much as I'd like, I think I end up sounding cleaner and more prominent than the old way.

You've got some options. You can get something like the Aguilar Tone Hammer, Pigtronix Bass Station, BassSwitch DI (which I use when playing ampless) or others that have an EQ or compression built into the unit to give you some kind of control. You can also run a small pedalboard with an EQ and/or other things prior to the DI box as well.

kohanmike
09-09-2015, 11:47 AM
Either there's no PA (like this next gig), or the board doesn't have enough inputs for our basses because we're usually the quick opening act and the headliner equipment is already taking up everything. Either way, I need to be self contained. I've even come up with a solution to get on and off the stage really fast; I leave the amp in my shopping cart with my music stand and bass hanger attached so all I have to do is roll it on stage, plug in a/c and stand behind it, unplug and roll it off.

Yup , I do use a pedal, and I'm pretty happy with my tone. Sometimes I just miss twiddling the knobs on the amp.

If that amp isn't loud enough you're either in the loudest uke group in the world or you're playing stadiums with no PA, neither of which works well. I bet you'll do well with that carvin. And if the uke group doesn't like it they can always provide what you need... ;-)

Thanks MR, I am looking forward to the amp taking care of business. There were over 50 of us at the last gig, and no one has made any negative comments, other than that they couldn't hear me, it's just that there are times when there will not be a PA, and if there is, we might not be able to plug in, and also that we have to get in and out quickly. The more I post about the amp, the more anxious I get waiting to use it.

I made the clamps for the music and bass to go on a stand, then I realized because they could clamp anywhere and I could use them on the cart. There's also a clamp for an iPhone to record audio, or even video come to think of it. What's ironic is, I'm having an On-Stage amp stand modified to be more compact and portable, but I don't think I'll be using it much now.

This was actually the last day I didn't have a uke bass, I made my acoustic the next day and bought the solidbody a few weeks later. The amp and cabinet in that picture is 25 lbs total, 1 10" speaker. This was at a casino gig, so there was plenty of PA support, and even better we didn't carry it or run it!

Very good, I always appreciate useful modifications.

More info on the Carvin amp; with the fact that a second 8 ohm speaker will get the amp to 250 watts, and that I'm seeing so many rigs with two speakers, and that Carvin is having a sale, today I ordered a 115MBE with a neo speaker for $308.53 out the door. If I thought the single 15" speaker was going to be really good, I feel that the dual speaker should be terrific. Should receive it with a couple of weeks.

Can't beat the price. Not sure I get how two speakers is going to help a bass. Or how it's going to solve your group not letting you turn it up...

I didn't say I couldn't turn it up, it's that I couldn't plug into a PA at the venue. The two speakers will bring the amp to it's maximum power, 250 watts, and the more air moved by the speakers, the better the sound. My other amps don't have the ability to be loud enough in an outdoor larger setting, that's the main reason I went with this Carvin system, but the second speaker will only be for a really large venue. I bought it more for the price while it was on sale. Most of the time I'll use the Phil Jones for indoor smaller gigs, the Carvin amp for larger outdoor gigs, and the amp with second speaker for those occasional big gigs.

You should also get an svt so you can do your uke tribute to heavy metal!

I received the amp and external speaker earlier, wow do they sound good, but the gig on the 26th will be the real test. The amp with neo speaker and my Sony wireless receiver weighs 25 lbs. The external unit weighs 22.8 lbs. The amp fits perfectly in my cart, and even stacked, they can be carted around.

Dang that looks really good Mike. This is for outdoor venues and the D4 for practice and small indoor gigs? Getting my preamp tomorrow so will finally find out if the passive pickup is any good.

Yes Pat. I've been using the D4 in our rehearsal room, which is on the larger side with about 30 players and the leader patched into a Fishman Loudbox mini (60 watts) with mic too, the D4 does very well, as well as small gigs coming up.

The bass I have uses a piezo pickup. For the Double4, the impedance should be on the high switch. By using a preamp to boost the gain, would the setting still be set for hi imped. or down to low because of the preamp ampimg more gain. There's more volume on the high. Clarity is the same or close to it.

In all honesty, it doesn't matter. The switch acts much like a dB pad does on other amps, so used in conjunction with the input level knob, you can do whatever sounds best to you and doesn't clip the signal. I usually keep it at the HIGH setting for all my instruments; active, passive or using a preamp to boost the signal.

The only instrument I use the LOW setting on is my NS Design Electric-Upright Bass, because that bass has such a hot signal (the onboard pre is 18v), it'll clip it at really low levels. That bass is also the only one I don't keep the onboard volume at 100%, because it's such a hot signal.

Thanks Jon. I thought so but wanted clarification. So much to learn with this new toy but sure am enjoying hearing the bass as it should be heard. I'll post a sound sample when I figure out how to do one of how it sound with/out the preamp. I really like the Mogami cables.
