Hotone Ampero II Stomp

The Hotone Ampero II Stomp is a second-generation multi-effects modeler and effects processor in a compact, pedalboard-friendly chassis¹. It packs amp modeling, cabinet simulation, effects, IR loading and flexible routing into a stompbox-format unit built around Hotone's CDCM HD and F.I.R.E. modeling engine². Hotone announced it in November 2021 as a comprehensively refreshed follow-up to the original Ampero, counting on a more powerful tri-core DSP platform to give it a competitive edge³.

The controls: 4-inch touchscreen and footswitches

Much of the editing happens on the unit's 4-inch touchscreen, which has a newly designed interface for intuitive editing³. The screen is central to how the Stomp works day to day: you drag blocks, adjust routing and build presets on it.

The unit has four assignable footswitches with multicolor halo LEDs, offering two working modes with customization support⁶. These are PATCH (preset) mode and STOMP mode: PATCH mode cycles through presets, while STOMP mode turns individual effects on and off like a conventional pedalboard⁶. Bass Musician Magazine's reviewer found the onboard footswitches responsive and functional². There is also a 1/4-inch input reserved for an external expression or control pedal, so you can adjust parameters on the fly³.

Amp models, effects and Celestion IRs

The Stomp's model counts come from its launch coverage: 87 amp models, 68 cab sims and over 60 effects, with access to over 400 effects from an expanded effects library³. You can run up to 12 effects modules simultaneously, arranged as a customized dual effect chain with multiple serial and parallel signal routing support³. Preset storage covers some 300 presets spread across 100 banks and three patches³.

For speaker simulation, Hotone teamed up with Celestion: the Stomp comes loaded with 20 Celestion speaker IRs, each powered by Celestion Digital, with 50 custom slots available on the unit for your own IRs³. The modeling itself uses Hotone's CDCM HD + F.I.R.E. technology, which combines white box and black box modeling approaches¹.

Connections and USB audio

The Stomp is well connected for a compact unit. It has stereo I/O jacks and stereo FX loop jacks⁵, an auxiliary input for adding external audio, a headphones output for silent practice and monitoring, and a USB port for managing your effects and sounds³. It can be used as an 8-in, 8-out USB audio interface, allowing you to record direct to your DAW and to reamp³. Bass Musician Magazine highlighted the balanced outputs, stereo capability and MIDI implementation as making it practical for professional stage use².

History and versions

The Ampero line began with the original Ampero, and the Ampero II Stomp followed as the second-generation modeler and effects processor, housed in a lightweight aluminum enclosure with the four-inch dynamic touchscreen¹. Gearnews reported the launch at EUR 499⁵, MusicRadar at £429³, and Guitar World at $499¹.

The Stomp sits inside a wider family. The Ampero II is the full-size second-generation unit, and the Ampero II Stage, unveiled in October 2023, is the third iteration of the Ampero II collection, following the Stomp and the Ampero II Mini⁷. The Stage ups the control surface to eight assignable footswitches versus the original four, with one serving as a default selector between Patch and Stomp modes⁷. There is also the smaller, cheaper Ampero Mini.

At launch, MusicRadar positioned the Stomp as a natural competitor to units such as Line 6's Helix Stomp, Headrush's MX5, and Mooer's GE300 Lite³.

What reviewers said

Bass Musician Magazine's Cláudio Ribeiro reviewed the Stomp for bass players in May 2026, praising its routing flexibility and amp models while noting DSP limits and a smaller bass ecosystem than competitors offer. On the amp models²:

The review found over 80 amp models on tap, along with a large effects library, stereo operation, parallel routing, MIDI support, USB audio interface functionality and up to 12 simultaneous effect blocks²³. The unit remains available, including online at Amazon.com².
