I have an Epi LP Standard. I recently upgraded the Pickups to a Seymour Duncan JB in the bridge and a '59 in the neck. I would like to upgrade the pots as well. Does anyone have any suggestions on how I could get better volume and tone control? I have been reading a lot about potentiometers and the pots in the guitar now are 500K Linear and Log pots. Any help or information would be greatly appreciated.
