Hotone MP-300 Ampero II Stomp Processor Pedal

Overview by Hotone

“Upgrade” is more than a 7-letter word. It embodies the continuation and evolvement beneath the surface, and embraces revolution and creativity outside the box. It’s what Ampero II Stomp does. Throughout years of grinding to establish its core technologies from empirical practice, Hotone team proudly presents this soul partner for your sophisticated taste in the sound of the music.

In the past, digital multi-effects were criticized by the public, with many claiming they have a "dull, lifeless sound". Our aspiration is to eliminate this stereotype and devote our best efforts to making them sound authentic and genuinely feel like a real amplifier. Based on decades of research and empirical practice in the field of digital modelling algorithms, the Hotone team is able to unveil and unbox the ultimate weapon - the CDCM HD + F.I.R.E modelling technology.

This technology models every component of the original device, building a model that tracks the dynamic variations of the instrument’s input signal. This maximizes its ability to reproduce the exact sound characteristics of the modelled object, delivering a more dynamic, deep, in-the-moment tonal feel. International professional musicians who have embraced this technology are enamoured by the unbelievable realism of the tone.

Dual effects chain, more tonal variations.

Ampero II Stomp introduces a highly customizable dual effects chain supporting multiple serial/parallel signal routing, up to 12 effects modules can be used simultaneously. Try it as you see fit.

8-in/8-out audio interface, new sparks for home recording.

Ampero II Stomp is a complete 8-in/8-out USB audio interface. Whether you want to monitor wet and record dry, record wet and dry at the same time or reamp, you've got it all in Ampero II Stomp.

Glossy touchscreen, smoother navigation.

The Hotone Ampero II Stomp is imbued with a fresh UI design to make things more accessible. Besides the touchscreen, editing overall settings and switching patches can be also managed with ease.

Improved IR performance, new step for realistic sound.

Ampero II Stomp now supports up to 2048 IR sampling points, doubled up from the previous generation, and can reproduce captured cabinets and studio acoustics with greater precision. 20 classic Celestion® speaker IRs powered by Celestion® Digital and 50 more custom IR slots will hugely rejuvenate the energy of your music.

60-second stereo looper, new inspiration generator.

A built-in stereo looper supports max. 60 seconds stereo recording, backed up by handy functions such as undo/redo, 1/2 speed, reverse record/play and more.

Compatible Win/Mac Software.

Connect to your desktop or laptop and launch the editor software, with more specific effects descriptions, more straightforward patch editing and more effective patch management.
