I recently bought a new Picture wah and was very disappointed to find that it was WAY noisier than my RMC-1 when used with my various OD and dist. pedals. Is this noise ( like a low 60 cycle gain hum) due to the differences in the 'core halo' vs. the 'stack of dimes' inductor? I am powering all of my pedals with carbon batterys and my signal chain goes like this: Strat > Teese wah > BBOD > Honey Bee > Blues Devil > DRD > Fargen Blackbird. The noise from the Pic wah is directly proportional to how much distortion I have dialed in from my other pedals and I am not 'stacking' them. I would appriciate any input regarding this topic. Thanks, Perry D.
