It’s designed to work seamlessly with BIAS Amp to create your ultimate guitar amp, and with more than 3 million users worldwide, JamUp has been featured in Macworld, Premier Guitar, Guitar World, Guitar Player and more.
The original JamUp comes equipped with one amp and six effects. JamUp Pro gives you the power of six amps and 16 premium rack and stomp-box effects, including distortion, compression, tape delay, tremolo, and spring reverb. Both JamUp and JamUp Pro include Jam Player, phase sampler, tone sharing, preset manager, optional 8-track recorder, live view, tuner, and metronome.
With its easy-to-use drag-and-drop interface, JamUp enables you to arrange a studio-quality collection of amps and effects models into your own custom signal chain. Get the optional expansion packs for access to a mind-boggling 52 amp channels and 50 classic effects.
Each amp model has been developed using Positive Grid’s MESH multi-stage modeling technology, and has been meticulously measured and analyzed against actual hardware. With its dead-on accuracy and tube-like touch and feel JamUp delivers vastly-improved sonic performance over other mobile digital amp modelers.

Hi! Please do write us on https://help.positivegrid.com/hc/en-us/requests/new and tell us more about the problem on your device! We will follow up and find out the solution for you!
Pretty fun stuff! Sounds really good out of the box and sounds even better with more tweaking! I’d be careful if you have active pickups...sometimes it’s too hot for the app and you get a really loud screeching feedback sound. But overall really neat! I use an irig2 into my iPhone SE. I do recommend getting the bias app with this too. That will REALLY make it sound better. I use it for recording and just playing late at night without disturbing anyone!

Hi, we are really glad you enjoy JamUp. Cheers! :D
Cool app but bad support response
I like the app and effects. I've bought a few effects add-ons. I also bought a Griffin Stompbox pedal to use with it and it's weird trying to understand some aspect of how the switching works between the Stompbox and JamUp effects. I've emailed them twice last year about it and never got a response or acknowledgement. So good luck if you can't figure something out and need help and can't find other users with the same problem in their forum.
