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 dramatically improved sonic performance over other digital amp modelers.

Save money on expensive pedals!
Every time I go to guitar shops and see those expensive pedals makes me think Jamup saved me a lot of money. Great job Jamup!
Hi, thanks so much for the feedback! Glad you enjoy JamUp! :D
An amazing app for any guitarist. I highly recommend buying a digital interface rather than one that plugs into the headphone jack to avoid excess noise which is amplified by high gain amp sims and pedals.
Hi there, thanks a lot for the feedback! We're really glad that you enjoy JamUp! :D
I purchased JamUp Pro and a ton of amp and effects models. I have my presets all setup and loved the way it functions. However, I just bought a new iPad Pro and now it won’t let me use the JamUp Pro plugin with GarageBand. I get the warning “App not available. Inter app audio app you have selected is not available at this time.” How do I fix this and get my JamUp Pro plugin working with GarageBand again?
I purchased JamUp Pro and all of the existing amps and effects for nearly $100. Now the app won’t even work as a plugin. I’ve been forced to pay all that money again for standard JamUp and its amps/pedals. So I spent nearly $100 and hundreds of hours perfecting my personal presets, only to have the app self destruct. I’d been hoping that it was simply a bug that’d be soon fixed but it’s been non-functioning for several months now.
I am interested in purchasing Bias FX but this current problem has me hesitating. JamUp Pro has been my absolute favourite. The app is superb. I’m a frustrated that I had to buy it all a second time, using the same Apple account.
Any refund options for the nearly $100 off faulty software ?
