Greetings! I just picked up an Orville Les Paul last week. It replaces an Edwards model I had owned for a few years, but never totally connected with. I'm really enjoying it so far. The neck is a bit thicker than the Edwards and it was already upgraded with Seymour Duncan Slash pickups. The neck is quite loud and I am having to get used to rolling back the volume quite a bit. I am wanting to upgrade the standard knobs with something more vintage-style: gold top-hat w/silver reflectors. I'm not sure which after-market brand will fit over the existing pots. Can someone point me in the right direction? Thank you!
