Hi, I recently purchase a LD150 amp and a FBV Express foot controller, but I can´t find the way to activtate the Wah control, it just stay in the volume control, and the manual don´t say anything about it, anybody knows how to do it?
Step down on the expression pedal (hard). You should be able to get the Wah LED to activate. Put your weight down on the toe-down position, though. Especially if it's a brand new pedal.
