I am completely disinterested in using solid state distortion with valve amplifiers. I bought an EHX Soul POG awhile back and found the Soul Food side to be totally useless. I ended up selling the pedal. Now, I know the Soul Food is not a bona fide Klon Centaur but I doubt the real deal would be that much more impressive. If I need clean boost, I engage my LPB-1. For distortion, I engage my English Muff'n.
