Re: DS-1 and SD-1
IMHO, I've found that both of these pedals (in their stock form) are anything but smooth. I had mine modded by a fellow at the Fender Forum and my favorite is the SD-1. He managed to take away the fuzzy top end and replace it with a nice underlying crunch. I know a fellow here does mods on these pedals and people here have been very pleased with the results.
