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!

Great Sounding Amps

The high gain amps sound amazingly great. Bought the Dual Rectifier, Soldano and Marshall 900 and their required cabinets and I am more than happy. Did some quick tracking in GarageBand on my Mac and I am blown away how good they sound in a mix. I used an iRig HD interface to my iPad Air 2 and did not experience any latency at all. I was able also to integrate my Apple camera adaptor so that I could charge my iPad while tracking with the iPad and amps.

Compared to other amp sims, I wish I would have found this one first. It's not overloaded with options or distractions. Set up the pedal, amp and cab and dial in the delay and reverb and you're off and running. The controls are responsive and move smoothly.

I seriously do not know why this amp sim isn't more popular. I've tried all the big-name sims and this one is way better sounding, more cost-effective and lets you save your settings as user presets. Try it out for a few dollars and see for yourself how good it sounds.

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.

Doesn’t work with GarageBand

App doesn’t work with GarageBand as advertised. Even followed their onscreen steps to connect to GB via Inter app audio, but GB doesn’t recognize it as an input, there’s no signal.

As a stand-alone app, it sounds nice. Only get 2 amps though, have to purchase others.
