I recently got a RMC Joe Walsh Wah, and am trying to mount it on my Pedaltrain Jr that has a PedalPower 2+ mounted underneath it, and no matter where I put the Wah, I get an excessive amount of buzzing whenever it is engaged. I've tried powering the wah with the PP2+ as well as on battery, and it makes no difference. The buzzing goes away the further the Wah is from the PP2+, and if the PP2+ is off there is no buzzing at all. I've even tried installing a Stompin' Grounds mounting plate/EMI shield on the Wah, and it hasn't made a significant difference. I don't think it makes a difference, but the PP2+ is installed so that the DIP switches are facing the floor. Anyone have any ideas? Am I screwed and my wah is forever banished to the floor?
