Classic Vibe 60's questions:
1. What have you guys replaced the stock tuners with?
2. Which other model pickguards will fit both the 60's P and J basses?
I replaced the stock tuners with Invalid Link Removed. These tuners were "Perfect Fit Replacement Parts" and required absolutely no modification or adjustment to the headstock. I have read others recommend the HB7 tuners for the CV P but the HB1 tuners and BT1 detuner are what you need. If you don't upgrade the tuners and decide to add a just the detuner, I did notice that the shafts of the paddles are shorter on the Hipshots than on the stock tuners so that may, or may not, be an issue to you.
I don't know about the pickguards but the P bass guard looks pretty standard.
), but they're both neck-sized. You'd need to find a similar bridge-sized one to best compliment it. But don't take my word for it…ask anyone who owns a CV Jazz about the sound they get out of them.
