My new Delta Blues, Peavey, pops lately when I turn it off. I checked everything I could think of but you guys, as usual, have given me some more things to check. I have a fan plugged into the same power strip. Might be related.

My gut feeling is that it is a ground problem of some sort.

Probably should check it on a dedicated grounded extension cord before taking it in for warranty repair, if covered under the warranty.

My cell phone always chirps thru my tube amps every time the system checks in with the phone but the phone is within four feet of the amp and inches of the guitar cable.
