For a long time I've been having strange tone troubles. My humble performing set up is this: Hohner B2A (modified)<--->Z. Vex Fuzz Probe<--->Sansamp Bass Driver<-->Boss ODB-3<--->EHX Holy Grail<--->Pignose B100V (combo) I noticed that after I'd power up and play with sweet, clear tone for about a minute and a half, all the sudden I'd lose gain and clarity and things would go mushy. I finally traced the trouble to my Holy Grail. The Holy Grail had given me troubles before; every now and then it would go wonky, and the blend knob wouldn't...well, blend. It would either be nothing but reverb or nothing but dry. I found that if I unplugged and replugged the power supply, it would 'reset' and be fine again for a while. I thought this problem was unrelated to my tone troubles, but I finally took the grail out of my pedalboard, and problem solved! I was wondering though: has anyone else had this sort of trouble with the Grail or any other pedal? And if so, what is it?
