Loud popping sound when I turn on pedal with my wireless.

Mods please move if this isn't in the correct Forum.

I have an Audio-Technica wireless system for my bass. When I turn on my BIG MUFF there is a very loud POP! What can I do to stop this? It doesn't pop when I turn on my wah, just the BIG MUFF. What should I do?

Usually such pops are caused by sudden DC voltage shifts. This is very common in true bypass pedals, but the cause is not always obvious. The interaction between various pedals can make things worse or better, depending on which way the wind is blowing and how many sheets of loo paper you used on the 13th of March 2001...

Sounds to me like you big muff is true bypass, and it's in the signal path directly after the wireless receiver, and the receiver outputs a signal with lots of DC. Try swapping the order of your pedals, or put a non-true-bypass pedal between the receiver and the big muff, just to see if things change.

nifty, not to rain on your parade...I've had it happen with several "real" stomp switches, like a Phase 90 and a Sovtek Small Stone (the big green one which was definitely NOT TB).

No rain here... I did start out saying "...very common in TB..." and then just assumed the big muff was TB when it needn't have been.

You're correct and I should have pointed that out, the same thing can happen with any mechanical switching system - true bypass or not.

Forgive my TB bias!
