Hotone Ampero II Stomp Portable Multi-FX Modeller Pedal

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.

Ampero is more than a series. Since launched, the Ampero series has earned a reputation for sound performance and user interface design.

In the past, digital multi effects were often criticized for producing a dull, lifeless sound. The goal here is to sound authentic—like what you would perceive from a real amplifier—using Hotone’s CDCM HD + F.I.R.E modeling technology.

Ampero II Stomp implements the tri-core digital platform and independent AD/DA from ESS Sabre Series, combined with CDCM HD and F.I.R.E modeling technology for more musically dynamic and vivid tones.

Dual Effects Chain

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.

8-in/8-out USB Audio Interface

With the 8-in/8-out USB audio interface function, you can monitor wet and record dry, record wet and dry at the same time, and reamp.

Glossy Touchscreen, Smoother Navigation

Ampero II Stomp features a touchscreen and an updated UI for easier editing of settings and switching patches.

Improved IR Performance (Celestion)

Ampero II Stomp supports up to 2048 IR sampling points (doubled from the previous generation). It reproduces captured cabinets and studio acoustics with precision. It also includes 20 classic Celestion speaker IRs powered by Celestion Digital, plus 50 additional custom IR slots.

Effects Library

60-Second Stereo Looper

A built-in stereo looper supports max. 60 seconds stereo recording, with 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 for more specific effects descriptions, more straightforward patch editing, and more effective patch management.

Lighter Design

The shape of Ampero II Stomp is designed to fit as a stompbox on a pedalboard matrix. It balances portability and practicality.

Richer I/O Jacks

Hello, Stereo In/Out. Pair up with more instruments/pedals/amps. Stereo FX Loop jacks provide additional routing/tonal possibilities. EXP/CTRL and MIDI In/Out offer expanded control options.

Application Scenarios

Connect to the Input of amps

Connect the output of Ampero II Stomp to the input of your amp, like using an effect pedal. You can also use external controllers or other pedals via the FX loop if needed.

Connect to the FX Loop Return of amps or the Input of pure post-stage power amps

When connecting to power amps, you can adjust Ampero II Stomp parameters like a real amp. When connecting to an FX Loop Return jack on certain guitar amps, use the specially designed PRE AMP modules for maximum enjoyment.

Using with other stompbox effect pedals

Place Ampero II Stomp on your pedalboard. Set the bypass mode or FX loop depending on your needs, then use it alongside your other pedals.

Connect to full-range audio devices such as mixing consoles, audio interfaces and headphones

Ideal tones can be used for home practice or live gigs.

Connect to your desktop/laptop as an audio interface

Connect the USB jack to your computer, connect monitors, and use the software and driver settings. Your mini music studio is ready.

Using the Aux In Jack

Use an AUX cable and connect Ampero II Stomp to your smartphone or music player. Practice and improvise with backing tracks or a metronome.
