ME-20: The Expression Pedal

Tags: me-20,exp,wah
The ME-20 features on on-board expression pedal to control volume, as well as a wah effect. The built-in switch underneath the expression pedal makes it quick and easy to toggle between controlling volume or wah. Here’s how:

1. With the ME-20 on a hard floor surface, press the expression pedal all the way forward, and then give it a stronger push.

When the WAH indicator lights up red, the pedal is controlling wah. When the indicator is unlit, the pedal is controlling volume.

Each time you press the pedal forward and give it a solid push, it toggles between wah and volume.
