I have a BC Rich Mocking bird that was purchased in 1983. I would like to know what all the knobs & switches do & how to get the best sound. I understand these: There's a Volume Knob, Tone Knob, Pre-Amp Switch & Pre-Amp Volume knob. 5 way Tone Control Knob Getting confused w/ these: 3 switches that have something I think to do w/ polarity & making the double humbuckers sound like single coil pick-ups? Thanks, Sherri Z
