I've never been able to get my 76 P-Deluxe to sound like it once did. A couple of years ago, the tone pot went south and I replaced it with another 500K. Didn't sound the same. Then I had to change the cap. Now it's really not the same. Any P fans out there who could tell me what cap value sounds best to them, assuming you have a split pup at the neck and a jazz at the bridge? I am also not opposed to changing pups at this point and would like to know if there are any "standards" out there that many have migrated to. I play mainly r&b and edgy blues. I love this bass, but I'm running out of ideas.
