I've just started playing bass after a few years of guitar. I had a P Bass copy that I refinished and upgraded. I changed the pickup to a Dimarzio Split P. However, I think the wiring went wrong somewhere. I think I may have overheated the capacitor in an effort to get the darn solder to stick to the back of these pots. This is what it sounds like with both the volume and tone knobs dimed: http://www.lightningmp3.com/live/file.php?fid=6090 (excuse my poor playing) This is the bass DIed into my mixer, then into my sound card, with no processing done. It sounds like the tone knob just isn't doing it's job properly. I used this schematic to wire it, and everything is exactly the same, which is why I'm lead to believe one of the parts is bad: http://www.fender.com/support/diagrams/pdf_temp1/basses/0136100B/SD0136100BPg2upg2.pdf Also, when the volume knob is all the way down, the volume is not completely cut out. It's still quite noticeable. Any ideas as to what the problem may be?
