It all starts with great tone, for free. Use the Compressor to condition the dynamics of your guitar signal, boost your level, or overemphasize to add sustain. With the Amplifier, create tones ranging from classic rock and blues all the way to alternative and heavy rock, with enough gain to spare. When you’ve dialed in the perfect sound, save it as a preset in the virtual Floor Controller for instant recall.

When you need more options or want to expand your creativity, head to the Gear Shop. You can buy amplifiers, cabinets, and pedals individually or subscribe for an inexpensive all-access pass that includes all future updates and products. Get fuzzed out and sound like a classic rock hero or an early punk rocker, use flange to unleash the eighties, and everything can always use more wah. Stay tuned for new products and updates.

Get this Amp Sim

The amp sims in this app are amazing and worth every penny it should be in every iOS guitarist arsenal. If I could make 2 small suggestions. First Midi support so it can be used as a live gigging amp. Secondly the ability to place stomps after the cab for more tonal options and so delays and modulation effects don’t interfere with the cab impulses. This is far and away one of the best amp sims for iOS. I could go on about all of the amazing options like the pedal tweaking and cab mixing and how awesome that is. I just wish apple would promote this app more so more people could try it out. It feels like an amp and sounds amazing! I will be reviewing it for my YouTube channel this week. Cheers to the Developers and keep up the amazing work!

Thanks for the suggestions Joe! Regarding Midi support, can you send a note to with details about the Midi gear you're currently using? This will help us with testing.

Also, stay tuned for amps with fx loops!
