I just picked up a tubeworks blue tube and have a problem with it. The output is very weak. To match the unaffected signal I have to max the output of the pedal. Is this normal for these? I like the overdrive, but it is unuseable like this. So, I put an LPB1 in front and a Boss eq behind, and it sounds awesome, but that 3 pedals and a lot of real estate to get it to work. Any suggestions othet than what I've tried. Seems the output is way to weak.
