HEART POUNDING AMPLIFIERS ON THE GO 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. PLAY REAL – POWERED BY CDCM SYSTEM 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. THE ESSENTIALS 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!
