There was a thread awhile back about good pedals for Stones/Faces type tones. The EHX Nano Muff produces some nice dirty 70s rhythm sounds with single coils and Fender-style amps. I did this clip with a DRRI and two guitars: an Epi 56 Goldtop RI and a MIM Strat. Amp volume is all the way down. Guitar volume either 9 or 10. Not half bad for $40.
