G.K. 400rb issues

Ive noticed lately when playing my sound will drop off and become distorted, wiggle the input cord and it clears up then goes back to distortion? its not the cord as i have done all that! anyone?

then it's your input jack. take it in to an amp tech, shouldn't cost much to fix.

Better yet just take some electrical contact cleaner to the jack with a q-tip and it might fix it. If not then a resolder is probably in order.
