I need to know if this is a warranty issue, a known problem, or a just have to live with it thing. Any help you could provide would be great.

When I engage my big muff I get a loud pop. Same with disengage. When on, it seems to sound great. I notice no unusual noises. It just seems like it shouldn’t do that.

In case it makes a difference, I am using the original wall wart which is plugged into a pedal pad powered pedal board. it is in line with a ts9, mxr chorus, gigadelay, ibanez fl9, and a crybaby. Fender Strat on one end and a carvin legacy amp on the other. Pop occurs irregardless of other pedal activation and still happens when wall wart is plugged directly into wall.

Thanks in advance.
