Description
The Hotone Ampero Press 25kΩ Edition (SP-30H) is the exact passive volume/expression pedal built for hosts that specify a 25 kΩ expression taper, most notably Hotone's own Pulze Control.
Which Hotone Press pedal is right for you?
| Model | Best for | Wah | Expression pot | Power |
|---|---|---|---|---|
| Soul Press II (SP-20) | Players who want volume, wah, and expression from one passive-footprint pedal | Yes (WARM/CLASSIC + Q) | 10 kΩ | 9V DC or 9V battery, or fully unpowered as an expression pedal |
| Wong Press (SP-21) | Players who want the Cory Wong signature take on the same 3-in-1 platform | Yes (same WARM/CLASSIC + Q) | 10 kΩ | 9V DC or 9V battery, or fully unpowered as an expression pedal |
| Ampero Press (SP-30) | The simplest, cheapest way to add volume and expression to an Ampero-family unit | No | 10 kΩ | None – fully passive |
| Ampero Press 25kΩ Edition (SP-30H) | Hosts that specifically call for a 25 kΩ expression pot, such as Pulze Control | No | 25 kΩ | None – fully passive |
| Ampero II Press (SP-35) | Ampero II Stage owners who also want an independent momentary footswitch | No | 10 kΩ linear | None – fully passive |
| Tuner Press (SP-30T) | Players who want a built-in chromatic tuner in their volume/expression pedal | No | 10 kΩ | 9V DC required (no battery) |
Not sure which one matches your rig? Check the expression-pedal input on your Hotone processor: Ampero Control (EC-4) is rated for a 10 kΩ expression pedal, while Pulze Control (EC-2) is rated up to 25 kΩ – that is the one case where the pot value, not the model name, decides the right pedal.
Why guitarists choose the Ampero Press 25kΩ Edition
- Purpose-matched pot value: 25 kΩ expression taper hits Pulze Control's officially stated maximum expression-pedal pot resistance exactly, instead of relying on a lower-value pedal running under spec.
- Fully passive: no battery, no DC jack, nothing to charge or replace.
- Same proven Press-family enclosure and 100 kΩ volume pot as the standard Ampero Press, so it drops onto the same pedalboard footprint.
- Simultaneous volume and expression: the EXP OUT 1/4" TRS jack sends an independent 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 and switches
- 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.
Power and pedalboard compatibility
None required. Like the standard Ampero Press, this is a fully passive pedal with no DC jack and no battery compartment. Volume pot is 100 kΩ; the expression pot is the model's signature 25 kΩ value, versus 10 kΩ on the standard Ampero Press.

FAQ
Why would I choose this over the standard Ampero Press? Choose this edition when your host device specifies a 25 kΩ expression pedal – Hotone's Pulze Control (EC-2) officially states a 25 kΩ maximum expression-pedal pot resistance, which this pedal matches exactly. The standard Ampero Press uses a 10 kΩ expression pot instead.
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.
Will a 10 kΩ expression pedal work with Pulze Control instead? Pulze Control lists 25 kΩ as its maximum compatible pot resistance, so a lower-value 10 kΩ pedal will still function but will not reach that stated ceiling. The 25kΩ Edition is the value that matches Pulze Control's official specification.
What is the physical difference versus the standard Ampero Press? None documented beyond the expression pot value – dimensions (16.2 x 8.1 x 5.1 cm) and weight (430 g) are identical between the two editions.
Can this control volume and expression at the same time? Yes, the EXP OUT jack sends an independent 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.
