AD/DA, the Ampero II Stomp pushes the highly praised Ampero sound to a new level,

delivering a more detailed, organic sound with richer tonal dimensions. A highly

customizable dual-effect chain and more advanced functions will guarantee more joy

and fun. The pedalborad-friendly design also makes it great for pedal maniacs.





Touch the Marvelous!

Ampero is more than a series.
What makes a good digital effects processor? For us, it is so much more than delivering a high-quality sound.
In order to be accessible for more players to enjoy the pure simplicity of music, a good pedal needs a design as intuitive
and straightforward as possible, meanwhile maintains a reachable price.
Therefore, we carved this consensus into creating Ampero. 

Since launched, Ampero Series has gained the favor of the music professionals and hobbyists alike,
and earned the reputation for its sound performance and user interface design.
Ampero has become a striking force in the game.

In the past, digital multi effects in general were criticized by public that they produce a dull, lifeless sound.
Our aspiration is to eliminate this stereotype and devote our best efforts to make it sound authentic
and genuinely feel like what you would perceive from a real amplifier.

Based on decades of research and empirical practice in the field of digital modelling algorithm,
Hotone team is able to unveil and unbox the ultimate weapon, the CDCM HD + F.I.R.E modelling technology,
a combination and recreation to the mainstream white box and black box modelling technologies.

This technology models every component of the original device, building a model that tracks the
dynamic variations of the instrument’s input signal, which maximizes the capability for the reproduction of
the exact sound characteristics of the modeled object, delivering a more dynamic, deep, in-the-moment tonal feel.
International professional musicians who have embraced this technology are enamored
by how live play becomes so unbelievably realistic.

Tri-core platform,

New station for signal processing.

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


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.

Good news for y’all artists, Ampero II Stomp with the 8-in/8-out USB audio interface function will sure lend you a helping hand.
Whether you want to monitor wet and record dry, or record wet and dry at the same time, and of course reamp, which has been a trend, you got it all in Ampero II Stomp.

Glossy touchscreen,

smoother navigation.

Ampero II Stomp is imbued with the 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,
furthermore reproducing captured cabinets and studio acoustics with precision.
To add up, 20 classic Celestion® speaker IRs powered by Celestion® Digital and 50 more custom IR slots will hugely rejuvenate the energy of your music.

Lighter design,

welcome aboard.

The shape of Ampero II Stomp has transformed and transcended, and now fits perfectly as a stompbox in the pedalboard matrix.
By applying both addition and subtraction into our arithmetic, we put a higher build and take out the expression pedal
to find that equilibrium spot between portability and practicality.
