Through some careful hunting, I managed to find some knobs on the 'Bay that look virtually identical to the early (2nd gen) SB-1 plastic dealies:
(BTW, there were other similar ones out there. These were listed as ham radio parts, so it pays to broaden the search--just in case anyone else is on the hunt.)
So they arrived yesterday and they're pretty flimsy. I'm wondering if any of you (tramp?) can tell me if the G&L originals were the same way. These are entirely plastic except for the set screw and cheesy metal disc on top. I guess I was expecting some sort of metal sleeve that would slip over the shaft of the pot. These seem like they might not hold up so well over time.
So I'm having second thoughts on installing them. If the originals from G&L had more heft to them, I may keep looking (honestly, I'm not obsessive about this stuff, but it's a great time-killer hunting around for parts to make her look like she did when the factory gave birth to her).
But man, as-is, this bass is simply awesome. I paid less for this one than for any of my 3 other G&L basses, but it might win the tone battle. Certainly holds its own. And remember, this is without the MFD!
Don't rule out the Schaller pickup if you run across an older model, G&Lers. It's certainly a different sound than what G&L eventually settled on, but it's nothing to scoff at.
