Need some advice. Charvel Model 6, modified like crazy. Have a Duncan JB in the bridge and JB Jr in the neck position. Middle pup position empty. Replaced the three mini toggle pickup selector switches with one 3-way les paul style switch. Sound is bright. In another post there was a discussion about caps on the tone control and it was brought up that if you don't have a tone control at all the sound would be almost shrill. So I replaced the 500k volume pot with a 300k. Then I put a 470k resistor parallel with the pickups to ground. It's still just a tad bright. Can I put a second resistor on there? Or is there some kind of cap or something that I can put on the volume pot to simulate a tone control with a cap? thanks!
