I got my pedal out a while back and discovered it wasn't working correctly. I've had it a year or so and only used it for a few months without any problems. Since then it's been sitting on a shelf untouched. When I got it out to play with it, the volume was very low. Even pegged it is fairly quiet. Not really sure what has happened here. I tried a different tube with the same results. Any idea of what the problem may be? I don't even know if it can be repaired with all of the goop on the circuit board.
