Hotone Ampero Press SP30 -kitaravaikutus / expression-pedaali

Guitarists and bassists often struggle with pedalboard space and the hassle of multiple pedals for volume swells, expression control, and wah effects.

Tips

To get the most out of your Ampero Press SP30, place it early in your signal chain for volume swells or at the end for overall level control. When using it as an expression pedal, connect the TRS output to your device's expression input and assign parameters like delay time, reverb mix, or modulation rate. For wah use, simply engage the toe switch and rock the pedal to sweep the filter. The passive design means no batteries or power cables, so it's always ready to go.
