Hotone Ampero Firmware V3.8 & Editor V1.3.0

This Ampero V3.8 firmware update brings you new effects, more powerful features (e.g. 10 more user IR slots), optimized system performance and bug fixes. We recommend all Ampero users to execute this update for the best possible user experience.

IMPORTANT – Use V3.8 firmware with Ampero Editor V1.3.0 ONLY. The patches of earlier firmware versions are now NOT compatible with this V3.8 firmware due to the new features and changes, which means, after updating firmware, in some situations, your unit may not work properly. Please be sure to export all patches by using earlier Ampero Editor software before updating. After updating, you can import them via new Ampero Editor. The Editor will automatically convert your old patch files to the new version, so that you can use them with V3.8 firmware. If you accidentally updated to the new firmware before backing up your patches, you can still roll back to earlier firmware versions (load earlier firmware files when updating) before you edit/save patches with new firmware.

Ampero amp modeler & effects processor is a game changer. It’s heart pounding amp modeling and uber quality effects are powered by the new-gen CDCM HD (Comprehensive Dynamic Circuit Modeling High Definition) and F.I.R.E. (Field Impulse Response Enhancement) system, bringing you the absolute best the world has to offer. Packaged in a cool, thin case with a 4-inch hi-def color touch screen, Ampero delivers all the real sounds of rock past and present.

Driving Ampero is Hotone’s innovative CDCM HD (Comprehensive Dynamic Circuit Modeling High Definition) and F.I.R.E. (Field Impulse Response Enhancement) system. Built on Hotone’s powerful XTOMP platform, acclaimed Binary series, and breakthrough VStomp Amp virtual plugin, the new-gen CDCM HD & F.I.R.E. system showcases Hotone’s new high-shelf circuit modeling methods.

Mainstream modeling methods are generally based on static state circuitry modeling or “black box” theory, which just “come close” to the modeled sound. CDCM HD & F.I.R.E. employs a complex system based on dynamic feature modeling. In this matrix, the technology “rebuilds” the entire circuitry using modeled electronic components, resulting in a tone that is vivid, accurate and expressive. More than that, the new system enhances the relationship between amps and PA systems, delivering a realistic feel and response you’ve never before experienced on digital gear.


Ampero is powered by a huge dual-DSP platform running Hotone’s proprietary CDCM HD & F.I.R.E. modeling system.

Main Processor: Analog Devices® SHARC® series

A powerful Analog Devices® 4th gen SHARC® series DSP is dedicated to the audio engine. Compared to XTOMP, this processor features increased performance and hardware-based audio processing accelerator modules, which makes it easy to handle multiple XTOMP-grade high quality effect algorithms.  

Co-processor - NXP® RT series

The NXP® RT series crossover co-processor runs on the ARM® Cortex®-M7 core.
The co-processor not only helps processing audio streams, but also powers the touch screen display, USB I/O, and other functions.


Ampero employs a special design input mode selector that is designed not only for electric instruments, but also for acoustic players and even keyboard players! Simply connect your instrument to the input jack, select a mode for your instrument, pick a dedicated electric/acoustic/FX preset and you’re ready to roll.


No need to carry an extra acoustic anymore! Ampero comes with advanced “black tech” acoustic simulation algorithms. Used along with built-in acoustic IRs and acoustic simulation presets, you can easily transform your electric instruments into miked up acoustic masterpieces: steel string, nylon string, resonator, even ukulele!


Ampero can handle up to 9 effect modules simultaneously with its flexible FX1, FX2 and FX3/MOD effect modules for the best authentic stereo effect processing experience. Ampero shares the same growing modeling/original effects library as our all-powerful XTOMP pedal with even more goods:

242 effects

CDCM HD & F.I.R.E. modeling effects including: 64 amp models/60 cab models/100+ legendary pedal models/Next-gen mic position and microphone type simulations  
User custom IR loader with 3rd party IR support  
50+ Hotone original effects (incl. high quality drive/dynamic/filter/mod/delay/reverb models and more)
