Hey guys,

recently im getting a huge amount of feedback which didnt happen before,
i checked all the wiring at the back, resolderd one which killed most of the feedback
but im still getting loads,

what im confused about is that when i touch a wire at the back (while connected to the amp) the feedback goes down to normal level like it used to,

anybody got any ideas??

plus i joined a semi-pro gigging band recently and need to get this fixed asap. and im sure its the guitars fault, or possibly my metal zone. pleaaaase help...
