I used to use these pedals together and got really cool results. Sounded a lot like Timmy C stuff on the first Rage record. Unfortunately I parted with both pedals and now I'm trying to get that sound back. I just recently got a FX 25 (older 2 knob) on Ebay that came with a DOD Grunge distortion pedal. These combined didn't do anything cool. Do you guys think it's because of the Grunge, or the auto-wah since maybe it has one less knob and I can't dial in that sound? Or both? I guess I won't know for sure until I get the ODB-3 and FX-25b back.
