I have a problem with my current guitar setup. Its a Kramer Striker 100st with a Duncan Performer invader in it. I swap pick ups all the time and this time is noisier. Every time the pick up sends out a signal there is this almost over powering hum or hiss that goes with every note. very annoying.
Any fix or suggestions? Should i check my solder joints? could it be from not soldering the end of the bare wire just in the middle?
