FYI - here are links to the Zoom and Digitech pedals I mentioned previously...

When I want to use effects (away from computer/tablet), I have many other choices (from having played guitar for over 35 yrs) but my current favorite is the Zoom MS-100BT ($149), it lets you use up to 6 effects at a time, is the size of a single pedal, and you can buy newer effects over time when they release them via your iOS device (typically for ~$1.99 each) and upload them to the pedal over BlueTooth. Since I got this pedal over 2 yrs ago, they have released almost 100 NEW effects, and about 3 times a yr they have a sale, and I've bought some and installed them to the device. Which is quite easy to do.
The reverbs, delays, chorus and other modulation effects are so lush and thick, while retaining great articulation and definition, that I can highly recommend this pedal. I bought mine from Sweetwater here:

Aside from the amazing sound quality, the other big selling point for me is to reduce the clutter and complexity of having INDIVIDUAL pedals, dozens of patch cords to hook them all together, as well as either individual 9-volt wall-wart power adapters, or one of the multi-power adapters like a Voodoo Labs OneSpot or similar. The Zoom MS-series all take 2 AA batteries and I use the Panasonic (formerly Sanyo) Eneloop batteries which last a long time between charges and also have a very low self-discharge when not in use. I have on pair in the MS-100BT, and another pair in the charger, ready to swap out, as this also eliminates any hum from ground loops if/when using a 9-volt A/C adapter.
I ALSO use a Korg Pandora PXMINI 'pocket' multi-effect into headphones with my Sojing Silent solid-body uke, which I've detailed over in this thread previously WITH PHOTOS of how I have it attached to the instrument for completely untethered practice.
This link starts you at my post, which is #7 in the thread: (but make sure you read further down the thread, as I reveal more details in subsequent posts)

It seems that Sweetwater no longer carries the PXMINI (other vendors might still have it, but I have not checked), but they also have a 'pedal' version of this effects unit which ALSO has a headphone output, which you can see here, and in fact is $10 cheaper than the pocket version:

Further, if you do not need/want the BlueTooth function, Zoom has the MS-50G ($99) and MS70-CDR ($129) which you can see here, as well as their other more expensive multi-effect pedals:

On each of the Zoom effects product pages, Sweetwater has a demo video or two, and there is a whole series of videos on YouTube showing the full instructions on programming and using these units (of course with full sound demos too), which I have to admit were key to me not feeling intimidated before buying it, as you get to see just how it works without parting with your money, and then being faced with the fear of a giant manual to read, which these DO NOT have, the owners manual is actually very good, and has lots of pictorial diagrams that step thru the use of these pedals, and you can even download the manual direct from the Zoom web site, here:

PDF manuals for their other pedals are also available from their web site if you go to the relevant product pages and look at the DOWNLOAD section.
Also, MOST musical equipment manufacturers have the product manuals on their web site, which I always take full advantage of BEFORE buying a product, for if the product is a PITA or frustrating to use, then it will get shelved, and NOT used and the money wasted unless I return or sell it.
I am in no way affiliated with nor compensated by Sweetwater, just a VERY happy repeat customer.
Hope this info helps :music:
