About This Item
Description
The Hotone Ampero Press 25kΩ Edition (SP-30H) is the passive volume/expression pedal for hosts that call for a 25 kΩ expression pedal, designed first of all for Hotone's Ampero II Stomp.
It is the same compact 2-in-1 Press-family pedal as the standard Ampero Press, with a 25 kΩ expression pot instead of 10 kΩ. Independent volume and expression output jacks let you control volume and an expression parameter at the same time. Ampero II Stomp supports it from firmware V1.1.0 or above; it also works with other devices whose external EXP jack requires 25 kΩ, and as a standalone passive volume pedal.
Why guitarists choose the Ampero Press 25kΩ Edition
- Purpose-matched pot value: a 25 kΩ expression pot for devices that require 25 kΩ EXP resistance, such as Ampero II Stomp.
- Fully passive: no battery, no DC jack, nothing to charge or replace.
- Same Press-family aluminum alloy enclosure and 100 kΩ volume pot as the standard Ampero Press, so it drops onto the same pedalboard footprint.
- Simultaneous volume and expression: independent volume and expression outputs send an expression signal while the main path still carries your volume-controlled signal.
- Straightforward, mechanically simple control surface – treadle only, nothing to misconfigure before a gig.
Controls
- Treadle – the only control; sweeps the 100 kΩ volume pot and the 25 kΩ expression pot together.
- No footswitch, no mode switch – fully passive control surface.
Compatibility
- Ampero II Stomp – supported in firmware V1.1.0 or above.
- Other devices with an external EXP jack that requires 25 kΩ.
- Any rig as a passive volume pedal.

FAQ
Why would I choose this over the standard Ampero Press? Choose this edition when your host device requires a 25 kΩ expression pedal – Ampero II Stomp is the device it is designed for. The standard Ampero Press (SP-30) uses a 10 kΩ expression pot for devices rated for 10 kΩ.
Which Ampero II Stomp firmware do I need? Support for the 25kΩ Edition is implemented in Ampero II Stomp firmware V1.1.0 or above.
Is this pedal powered? No, it is fully passive with no DC jack or battery compartment, identical in that respect to the standard Ampero Press.
What is the physical difference versus the standard Ampero Press? None beyond the expression pot value – housing, 100 kΩ volume pot, dimensions (81 x 162 x 51 mm) and weight (430 g) are the same.
Can this control volume and expression at the same time? Yes, the independent expression output sends an expression signal to a second device while the main signal path is still volume-controlled.
Does this pedal have a footswitch? No, it is treadle-only, matching the standard Ampero Press control layout.
