I've got a possibly elementary question, but as I was rebuilding a pedal board tonight, I hooked up our Tech 21 Sansamp and Tech 21 XXL distortion pedal to the Voodoo Lab Power Pedal 2 and when I plugged it in to check it all I got a kinda bad buzz from the Sansamp and a reeeeeally bad buzz from the XXL. I plugged them both into jacks on the Voodoo Lab with the switches in the "normal" position, which as far as I remember (it's been 2.5 years since our last tour) is the way it was done previously. Am I missing something here? We leave tomorrow afternoon, so I'd like to solve this dilemma in the morning. Any advice is appreciated!
