Just bought this today, having some problems since the manual really doesn't say enough (for a noob like me):

- how do you get the tuner to work? ive pressed down on A and B channels and it does not switch to the tuner
-how do you get the delay effects to change? once i again i did as they said, i tapped the lit channel switch, but the delay/tuner meter remained dead as a doornail.

-do you change from volume to wah by pushing farther down on the pedal or what? didnt find an explanation for it in the manual

any help would be appreciated
