(I'll have to dig out my notes) My favorite overdrive pedal is a TS-9 reissue that was modded and switched to an LM883. The mod was done by an excellent blues guitarist here in D.C., Dru Lore, and I bought off him once he got bored with it. Anyway, the tone control was removed and the drive range significantly lowered. What he ended up with is a pedal where, with the drive down to zero and the Level halfway the sound was almost exactly like the dry signal (a little bit brighter), and with the Level control to full it was a clean boost up to maybe 2 1/2 times the dry level. The Drive control is limited to a nice blues overdrive (sort of like a tube amp witht the gain from 2 to 4) with extremely smooth tone. Anyway as a lead boost or blues overdrive it is the best pedal I've ever owned (and since Mike of "AnalogMan" was extremely helpful in removing the JFET switching so I could install a Carling DPDT switch, it has true bypassing). I keep putting off opening it up and making a schematic of the changes, maybe now it's time I done so (I just hate trying to get around those little dinky Ibanez boxes, may hat is off to all those people in Korea/Japan who assemble boxes for Boss and Ibanez). - Y.
