Ok, so last night at band practice, I noticed that when the trem pedal was in line with my Fat Boost, that it was cutting volume when it was off. Even when it was the ONLY pedal in line, it was still cutting volume when it was off. When I engage the pedal my volume came back up, and then had its beautiful trem sound. I tried it with a new 9 volt, and my One Spot adapter. I noticed this last weekend at my gig too, I had a red knob twin as backline turned up to 9, and was barely cutting through. I just thought the amp was shot. This is the first time I've ever had a problem with it. Usually it works flawlessly, and has been a great trem pedal for me. Any ideas what is going on??? Voodoo Labs are true bypass now according to their literature.
