ok this is really weird. I'm playing at practice right.. and i switch over to this clean sound on my amp, and all of a sudden it starts crackling at certain points of my song (most of the time when i play the open B string). thinking at first maybe i was too loud or i had too much highs or mids, i adjusted my settings and tried again..

i ignored it and went on with the rest of the song, but when i sang into the microphone, i got a big ZAP and it hurt like all hell.

Now i figure its gotta be an electrical prob.. so i flip the amps ground switch, both ways and then nuetral again.. no effect..

i unplug my amp from the power surge, and plug it back into a different slot in the strip and its fine.

but only temporarily. minutes later it starting crackling and i got electricuted once again. whats wrong and how do i fix it?
