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! FEATURES λ Grown out of next-gen XTOMP technology λ Simple-but-real guitar/bass amp simulator with easy-to-use UI λ Advanced CDCM modeling system ensures realistic playing experience λ Growing amp/cab library λ 23+ CDCM powered legendary vintage and modern amplifier models λ 20+ CDCM powered classic cabinet models λ Built-in delay and reverb effects with simple operation and huge ambience λ Built-in smart noise gate For more information: www.hotoneaudio.com

Cab ML is both a standalone app and an AUv3 plugin that provides a neural network for impulse response generation. By moving tags in a window you can change the impulse response in an interactive way. Underlying a neural network will generate an impulse response based on the position of the tags. Instead of trying out all your impulse response files through a classic impulse response loader, you can now find the right sound interactively by moving the marks until you like what you hear. Furthermore Cab ML also provides a poweramp with many options and a microphone reverb generator. The free version allows you to test Cab ML completely, but every minute the plugin will be silent for 3 seconds. To remove these limits there is a one time in-app purchase. You need an audio interface to connect your instrument to your Mac. Known audio interface brands for guitar or bass are for instance Focusrite or iRig. If you don't have an audio interface, you can use the AUv3 plugin in a DAW such as GarageBand or Logic Pro. Any (guitar/bass) sound you have recorded can be fed through the Cab ML audio unit.

Both are free to download. VStomp Amp HD sells 19 one-off in-app purchases and Cab ML sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
VStomp Amp HD holds the better App Store score, 4.2 against 4.0. Both are backed by a comparable volume of ratings — 10 and 4 respectively. Written reviews complicate that: 33% of VStomp Amp HD's written reviews are positive against 50% of Cab ML's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on September 29, 2026 and September 27, 2026 respectively.
