    The reason there's no depth and harmonic overtones is because your playing with the wrong amp and a cheap one at that. If your Ubass is an older model it's a passive pickup. Passive pickups usually need a preamp to boost the impedance. It's changes the whole sound and power of the bass. Newer ones have an active pickup with the preamp built it. I personally like the passive pickup, it seems to have more of a standup bass sound.

    Because of the great advice I got from the guys posting now,I recently upgraded my amp to a Phil Jones Double4 with a computer battery and Baggs preamp.. It weighs 8.9lbs.and puts out 75watts of pure bass thumpin sound. It changed my Chennel Bass from one of kind of whimpy to the best bass I think I've ever played in all my years of playing. the added Baggs preamp made a big difference in depth for the pieazo pickup.

    If you want a portable amp that'll do both instruments, a bit higher budget would make a big difference in what you're looking for. Played thru the proper amp, the Ubass rocks bigtime and cleans up the clarity of either instrument..

    It blows me away how a 75 watt amp can weigh that little and put out the clean sound and power it does. My Fender Rumbler30 weighed over 35lbs with 30 watts of muddy sounding wattage. If you don't need to go portable there are more options in your price range. If you're like a few of us in here, this won't be your last amp anyway; kind of like UAS.

Conversely, it seems hard to believe a bass amp would make a huge difference in producing both the fundamentals and the harmonic overtones of a Ubass.
    a ubass is HARD on the fundamental. I find it pushes my little amp much harder than a steel stringed short or long scale bass. Farting out happens at a much lower volume.

    As soon as that Pig Nose Hog gets pushed a little too much, it farts like crazy. The Phil Jones Double Four is clean all the way. It really is amazing how it producers a bass sound so well, and so incredibly small.

    Thanks to all for your contributions. Kohanmike's response made the most sense to me. In response to Patrick Madsen's comment, I am just getting started with this and have only heard samples. I have not played the Ubass through any amp, cheap or otherwise.

    Amplifying a bass, Ubass or otherwise, is all about moving air. In order to make it loud(er) you have to move a lot of air. There are two ways to do so. The first is with the volume of cone area - the bigger the speaker, the more air it moves. The second is with the travel of the cone - the further it can move back and forth, the more air it moves.

    Most small, portable amps use fairly small speakers due to space limitations. This leaves you with the need for a longer travel in order to move a sufficient amount of air. Unfortunately, most of the are spec'ed with shorter travel speakers which more accurately meet the frequency requirements of instruments which play in higher registers than the bass. The ones which are capable of the longer travel are generally quite a bit more expensive due to the tighter manufacturing tolerances required, the result being that a small, efficient, good-sounding bass amp is generally as expensive as normal sized bass rig if not moreso.

    This leaves us with the option of increasing the cone area, either by using larger speakers or more of them, both options which preclude smaller speaker cabinets. FWIW, the fullest, richest bass tone I've ever been able to achieve was with an Ampeg or Acoustic 8 X 10 cabinet. However, moving those things from gig to gig requires an amount of effort I am both unwilling to put forth or pay someone else to do.

    As far as amplified Ubass sound, I've found them to sound extremely full and detailed, given the proper amplification gear. At shows where I've used mine with electric cigar box guitars and even a when performing with a heavier alternative band, comments from audience members have provided similar observations. As a matter of fact, my little Rumbler has literally stolen the show a few times even when sharing the stage with some of the finest handmade custom CBGs.
    I too, have nothing of value to add to this thread...

    If you haven't seen my post earlier about the Carvin amp I bought, here it is in a nutshell; using the Double Four in a room with a small audience works great, but when I tried to use it outdoors with our leader on a PA (which I couldn't hook into), and an audience of about 200, it did not cut it.

    I have nerve damage in my neck and shoulders, so I looked for the best power to weight amp I could find. It turned out to be a made to order Carvin MB15 combo bass amp, 200 watts 8 ohm and a 15" neo 400 watt speaker. It weighs 24.6 lbs 12"D x 17"W x 18"H. I was so impressed with it, I ordered the matching extension 115MBE speaker, 22.3 lbs, which brings the amp up to 250 watts at 4 ohm with two 15" speakers, both $810 out the door, I mean it is KICK BUTT! When I use that amp with or with out the extension, I will use the Double Four as a monitor for myself and the band because I roll around the Carvin in an old lady shopping cart sitting in front of me with my music stand and bass hanger attached to it.

    A cool rig indeed. I am just starting out with uke bass so this is well beyond my ability and means at present.
