Hotone Ampero Press 25kΩ Edition Passive Volume & Expression Pedal
The Hotone Ampero Press 25kΩ Edition is a high-precision, passive volume and expression pedal engineered specifically for low-impedance signal chains, active pickups, effects loop placement, and digital multi-effects devices. Dressed in Hotone's distinctive black-and-gold chassis, this specialized 25kΩ edition maintains the rugged reliability and smooth treadle sweep of the original Ampero Press while catering to modern line-level audio routing.
Housed in a tour-grade, solid aluminum alloy enclosure, the Ampero Press 25kΩ provides smooth parameter sweeps and uncompromised signal fidelity without adding unnecessary weight or complexity to your pedalboard.
25kΩ Impedance Optimization & Dual Outputs
Engineered to prevent treble bleed and volume roll-off issues common with high-impedance pedals in active loops, the 25kΩ edition provides ideal resistance matching:
- Low-Impedance Volume Control: The 25kΩ volume potentiometer is perfectly calibrated for use after active pedals, in amplifier FX loops, or directly with active guitar pickups.
- Dual Independent Outputs: Features separate 1/4" Volume and 1/4" TRS Expression output jacks, allowing you to control audio volume and expression parameters on separate units simultaneously.
- 100% Passive Operation: Operates entirely without batteries or external DC power adapters, ensuring reliable performance anywhere.
Universal Compatibility for Active & Digital Rigs
While ideal for the Hotone Ampero series, the Ampero Press 25kΩ Edition is universally compatible with any keyboard, digital modeler, or guitar effect pedal accepting standard TRS expression inputs or line-level volume signals.
