HOTONE SP-35 Ampero II Press Passive Expression Pedal with Footswitch

Key points

A passive expression pedal and footswitch in one unit let you shape an effect and access footswitch control from the same pedal position. The HOTONE Ampero II Press is designed for guitar effects setups where expression and switching are both useful on stage or in the studio.

Its expression and footswitch connections use independent output jacks, so each function has its own connection. The passive design requires no power supply, keeping this control pedal straightforward to add to a setup.

A click-style footswitch is integrated into the pedal, while a high-quality potentiometer is designed for accurate response and long service life. The audio connection is 1/4-inch, with an analogue signal format.

How to use it

Connect the expression output and footswitch output to the corresponding inputs on your effects equipment using the appropriate 1/4-inch connections. The pedal then provides expression control and footswitch operation in one compact control surface. Because it is passive, it does not need its own power supply.

For a practical stage setup, place it where your foot can reach it comfortably alongside your other pedals. Use the expression function for effect-parameter control, and the integrated footswitch when you need foot-operated switching. In a studio, the same combination can keep adjustments and switching within easy reach while you play.

Compared with a standalone expression pedal that leaves switching to controls on the effects unit, the Ampero II Press brings both functions together. It’s a good fit if you want expression and footswitch control without dedicating separate pedal positions to each.

Best use cases

This pedal suits guitarists who want hands-on expression control as part of an effects rig, with footswitch access built into the same unit. The separate outputs make it practical when the setup has distinct expression and footswitch inputs. Check that your effects equipment provides the matching connections and supports the functions you plan to use.

On stage, combining the controls can make it easier to manage expressive changes and footswitch operation without reaching for the effects unit. In a home or recording studio, it offers the same direct foot control for shaping sounds while playing. Buyers also describe it as versatile and well built, with positive reports of use alongside different effects equipment. Feedback on its size is mixed, so its compact format is worth considering when planning pedalboard placement.

What to clarify

Does the Ampero II Press need a power supply? No. It has a passive design and does not require a power supply.

Are the expression and footswitch connections separate? Yes. The pedal has independent output jacks for expression and footswitch functions, allowing each to connect to the corresponding input on your setup.

What type of audio connection does it use? It uses 1/4-inch audio connections and an analogue signal format. Match the connections to the inputs on your effects equipment.

Is it worth it?

The Ampero II Press brings expression and footswitch control together in a passive pedal, with separate outputs for each function and no power supply requirement. For guitarists building a stage or studio setup that benefits from both kinds of foot control, it offers a practical way to access them from one pedal.
