Customer Reviews

Great tool for musicians!

I use this app for playing live and for recording. The base app is nice but the expansions really open up amps and pedals that give the right tones. Not every expansion is perfect, but the mix available gives nearly unlimited creativity. Compared to going to the local music shop and dropping well over $100 for a pedal, it really has a lot of value.

I use an iRig pro and Blueboard for interface and preset changes. Once you dial in your tones with a pair of studio monitors this app sounds awesome for direct recording. I have yet to experience hissing our noise in higher gain settings.

Flawless with bias

Works flawlessly with bias. Amazing amazing sound engine. Can't believe how much is sounds like the real deal. Fantastic. Definitely my amp sim of choice. Couple that with the ability to export amps from BIAS AMP into JamUp and you've got a powerhouse. Thanks positive grid!
