About This Item
Description
The Hotone Ampero MP-100 is the fullest-featured first-generation Ampero processor, with the largest effect library, XLR balanced outs, and full 5-pin MIDI – running on an 18V supply instead of the 9V used elsewhere in the range.
Which first-generation Ampero processor fits your board?
| Model | Effects | Built-in EXP pedal | Outputs | MIDI | Power | Weight |
|---|---|---|---|---|---|---|
| Ampero Mini (MP-50VN) | 199 | No | 1 x 1/4" TRS stereo (Y-cable for L/R) + headphones | None | 9V DC, 500mA | 529 g |
| Ampero One (MP-80) | 242 | Yes (EXP 1 onboard + EXP 2 external) | 2 x 1/4" TS + headphones | None | 9V DC, 500mA | 1202 g |
| Ampero (MP-100) | 270 | Yes | 2 x 1/4" TS + 2 x XLR balanced (ground lift) + headphones | 5-pin in/out | 18V DC, 500mA | 1408 g |
Choose Ampero Mini for the smallest, lightest travel or desk rig with USB-C and a single stereo TRS output. Choose Ampero One when you want an onboard expression pedal and dual TS outputs without paying for XLR or MIDI. Choose Ampero for the fullest first-generation feature set – the largest effect count, XLR balanced outs with ground lift, and full 5-pin MIDI – and remember it needs an 18V supply, not the 9V used by Ampero Mini and Ampero One.
None of these three has a device-side NAM module. Each imports up to 10 Sound Clone tone files (.nam, .tone, or .clo, one usable at a time) through Ampero Editor, and Ampero Editor V1.6.0 added the ability to accept NAM A2 files for that same Sound Clone workflow – a companion-app feature, not native on-device NAM A2 playback.
Why guitarists choose the Ampero
- Largest first-generation effect library: 270 effects across 9 simultaneous modules and 198 patches (99 user + 99 factory).
- Full XLR balanced outputs with ground-lift switching, alongside 2 x 1/4" TS unbalanced outs, for the cleanest connection to a mixing board or interface.
- Standard 5-pin MIDI in and out, the only first-generation Ampero unit with full MIDI, so it works directly with Ampero Control's wired MIDI OUT/THRU.
- Built-in expression pedal plus an EXP2/FS jack officially documented as "Perfect for Hotone Soul Press or Bass Press", and the Ampero Switch operating guide is written specifically for this unit.
- Purpose-built Ampero Gig Bag and Karat Cap accessories exist specifically for this model, both named directly on Hotone's own product pages.
Controls and switches
- 4" 800x480 touchscreen – full patch/effect editing.
- Volume knob and Main knob – quick level and menu control.
- 3 footswitches and a built-in expression pedal (EXP 1).
- 3-way input mode selector.
- GND LIFT switch – on the balanced XLR outputs.
Power and pedalboard compatibility
Runs on 18V DC centre negative, drawing up to 500 mA – note this is 18V, not the 9V used by Ampero One and Ampero Mini, so power supplies are not interchangeable across the first-generation range. Input impedance: E.GT 1 MΩ / A.GT 4.7 MΩ / LINE 10 kΩ, Aux In 10 kΩ. Output impedance: unbalanced 3.2 kΩ, balanced 2 kΩ, headphones 66 Ω.

FAQ
Does Ampero (MP-100) support NAM A2 on the device? No. Ampero has no device-side NAM module in firmware V5.2/V5.2A. It has Sound Clone, which imports up to 10 tone files (.nam, .tone, or .clo, one usable at a time) via Ampero Editor. Ampero Editor V1.6.0 added the ability to accept NAM A2 files for that same Sound Clone workflow – a companion-app feature, not on-device NAM A2 playback.
Why does Ampero need 18V when other Hotone units use 9V? Hotone's manual specifies 18V DC centre negative for Ampero (MP-100), unlike the 9V DC used by Ampero One and Ampero Mini – check your power supply before connecting to avoid using the wrong adapter.
Which expression pedal or footswitch is officially recommended? The EXP2/FS jack is documented as "Perfect for Hotone Soul Press or Bass Press", and the Ampero Switch operating guide is written specifically for this unit.
Does it have MIDI? Yes, standard 5-pin MIDI in and out, allowing direct wired connection to Ampero Control's MIDI OUT/THRU.
Is there a gig bag made for this exact processor? Yes, the Ampero Gig Bag (AGB-1) is officially "specifically designed for Ampero".
What is the difference between Ampero and Ampero One? Ampero has the largest effect count (270 vs 242), XLR balanced outputs with ground lift, and full 5-pin MIDI, but needs an 18V supply. Ampero One uses a 9V supply, has 2 x TS outputs only, and no MIDI.
