Thanks guys, I showed the spec sheet for the Tayda LDRs to some else who is building this pedal. He said the Tayda's will get you in the right ballpark but maybe not enough sweepin phase. He was ordering the LDRS from SmallBear and One set was similar to the Taydas and the other should give a real good sweep. (8002 and (9200) were the models and the 9200's were the sweepy ones
