I just picked up an old SD-9 today. I understand this was the precursor to the TS-9, and when SRV used the TS-9 and everyone followed him, Ibanez discontinued the SD-9. I was looking for a pedal that could do everything from light overdrive to full on distortion (was actually considering a Rat when this became available), and I think this might do the trick. Any tips or tricks? I play blues, tele into Pro Jr or DB115.
