Those are beautiful basses.
How are you guys going about getting 'off the menu' options? The K mod for the L series is well known, but still isn't a 'standard' option. This is the first time I've seen K switching on an
M series bass.
There are a fistful of options G&L doesn't have that I'd really like that aren't big deals given their existing capabilities - I'd love a pickguard on a JB-2, and black blocks/binding as a neck option. I'd fork up the cash if they'd do it.
I had an LB-100 in Old School Tobacco Burst which isn't a listed finish. That was something I found out about via word of mouth. The same goes for the SB-1 Fretless I just ordered in Whiskey. I found out about the fact that it was available now on all guitars from seeing a post on Basses by Leo and they did a few guitars (that weren't the Jerry Cantrell) model in that finish.
Unfortunately for blocks and a pickguard on the JB-2, they probably will never do that. Binding they do do however.
