I recently purchased one of these and returned it after having some distortion problems. The main issue is resolved with the replacement I received, but please help me understand something about this pedal. Either I am confused, paranoid or have a crap pedal. How should you run the volume and boost settings, do they even relate? Should the boost only be used to match the output between the 2 basses, and should it be turned off the rest of the time with the volume knob up full. I ask because when I plug my Alembic in if I turn the boost on, even a quarter of a turn, a low e or a chord causes distortion (plugged in to channel A, channel, and it is not a dirtier signal from channel B). However if I press the -10db button it resolves this. When I rang the shop they said I should be able to turn the boost on without causing distortion. If they had not told me this I would assume it should be flat unless needed and I am running a signal too hot when I turn it up? Please help me with this, is driving me nuts (or overdriving me nuts) Besides this I am wondering HOW you use your pedal, 2 basses, 1 bass with diffrent eq settings etc. Thanks guys.
