Wasn't too happy with its sound over the years, it had lost fuzz and sound(!) below 20%. With nothing to lose I took the back off and and adjusted trimpot 1 and 2 a bit. Trim 2 made the difference. Either I messed with it years ago and forgot what I did or it's drifted over time, but the pedal is back to early Page and Beck goodness!! Just throwing that out there on another secluded Friday night. Re-discover your old pedals!! Now I got my eye on my dusty Boss Flanger BF-2.
