The heart pounding VStomp Amp is now ready to go! Following the development of Hotone’s powerful and versatile XTOMP pedal and based on our proprietary CDCM system, VStomp Amp Mobile delivers organic, studio-grade sound quality and the exact character of legendary amplifiers – just the same as desktop version.


Unlike mainstream modeling methods based on the characteristics of a certain “state” of the circuitry, which just “comes close” to the modeled sound, VStomp Amp Mobile employs a complex system based on dynamic feature modeling. In this matrix, every single circuit component is ALIVE and performs like its original. The realness of the amp and effects tones has amazed XTOMP users worldwide, and now you can experience it on the go!

Behind VStomp Amp Mobile is Hotone’s CDCM (Comprehensive Dynamic Circuit Modeling) system. CDCM is built on an extremely complex dynamic variation matrix, able to realistically express every detailed change that occurs during the operational process of actual circuitry. This matrix will adjust its own modeling parameters and even framework based on the instrument input signal range, signal frequency, knob position, the instrument’s own impedance, and other variable parameters, all to achieve the closest possible characteristics of actual modeled circuitry.


No complex signal chain. No confusing customization or combinations.
You pick an amp model, pick a cab model, add some ambience – it’s that simple!
The less you tweak, the more you enjoy: just pick out your rig and ROCK!

Too much latency

The amps in general sound good. But i notice way more latency with this app than with my other guitar apps like BIAS AMP/FX, Amplitube, Tonestack etc.

I think the IAP prices are too high as well, bring the bundle price down some more too, fix the laency and i might consider this app some more. Otherwise i would recommend guitar players to invest their money in BIAS FX instead, which in my opinion is the king of all the guitar apps on iOS and a much better investment.

Brittle, Nothing Special, Unfinished

The noise gate doesn’t function properly.

It won’t allow input selection in GarageBand and fails to pass any signal.

Winding out the main outs of the amp head overpowers the output level adjustment.

Limited effects.

Not a rich harmonic content and transient response in the distortion zones.

No microphone selections and placement options.

A bit better than what GarageBand offers and as long as its free its better than nothing.
