    Alright, so I have an 88 Guild Pilot with active PJ EMGs. I absolutely love this bass but it was time to do some maintenance. I bought some new pots, strings, strap locks - all the little things.

    I decided rather than VOL-VOL-TONE I would move to a VOL-BLEND-TONE setup which has always made more sense to me. Anyway, after a few tries my wiring technique vastly improved and I did a more than decent job wiring it up. The connections looked good, it was time to plug it in.

    When I played it at first everything sounded perfect, well grounded (no hum or buzz), I was stoked. Then I went to turn the vol and/or blend pots and it was still scratchy. Can new pots be scratchy? Any Ideas? Is it my wiring job?

    I continued to play and it was sounding great until I really started to lay on the E string and my bass begun to distort. Only the E distorted and it was on any frets not just open string. Another note is that I don't hear the distortion when I pop only when playing finger style. Once again any ideas?

    I really appreciate any help, tips or advice. I was very proud of doing this myself, I feel like I know a lot more about my guitar and I feel a bigger sense of ownership and pride with it. Anyway sorry for the book!

    Take it Easy,

  2. New pots can be scratchy. Spray them liberally with contact cleaner and repeatedly turn them up and down until it has been worked in. Don't plug it in until the solvent in the cleaner has had time to evaporate.(should only take a few minutes) As for the distortion I would guess you have used the wrong ohmage pots. As I recall, the pots used with 80's emgs were something like 25 k, not the 250 or 500 k used with passive pickups. Check emg's website to see if you have the correct pots. They probably have schematics and pot ratings listed for the modifications you wish to make.

    Also wanted to say hello to a fellow Guild bass player. I have a 78 B301, one of the weirdest, but best sounding basses I have ever owned.
