My Guitar Amp Fm212 When I Plug Input Jack Makes Popcorn Noise Guitar Amplifier
Chosen Solution My guitar amp fm212 when i plug input jack makes popcorn noise, when i plug the guitar cable make hudge noise like pumping ur popcorns pumping…. when i take the jack of finish, i tested several jack cables and diferent channel amp even the pre in and makes same noise,… Sounds like you either have a jack that has broken the solder connections to the circuit board or a piece of a plug came off and is stuck inside the jack or else you have a jack that the plug is just too loose due to age and slight bending of the parts that make contact inside the jack....
