I love my hummingbird and i've had it for over 6 months...the other day i switch it on and there is no effect.
the signal passes through it but there is not effect. The only knobs that do anything are the depth (which operates as a reverse volume) and level (which operates as level) but nothing else has any impact.
I have a gut shot here, but cant see anything wrong with it...has anyone had this issue, and is it something that can be fixed?
