I have a bass that I want to change the pots and caps in. It's an Italia bass that's pretty cool but has lousy electronics. I'd like to use some Bourn pots and I have some Bumblebee's, Vitamin Q's and a few Black beauties. What pots? 250 or 500? What spec for caps 22 or 47? The pickups are 4 lipstick pickups, 1 for each string. I assume that they are wired as 1. Thanks in advance!
