Both my G&Ls that arrived a few months ago had a truss rod like that. Set deep, with some wood in the way. One had a missing signature on the custom build order sheet, and the other had the wrong model name on the custom order sheet. Both basses had the saddle lock screw and nylon insert missing. One of the basses had a bad preamp as well.
Greg @ Rocketmusic sent me both a new preamp and saddle lock screw sets, and I realize stuff like this CAN happen. Trussrods isn't a huge problem, they work just fine and adjusting with a ball-end key isn't too difficult. But I feel I've been a bit unlucky with these two, and I'm not the only one it seems. I've got a guitar due any day now, so I'm a bit excited to see if everything is okay with that one.
But, still... Once the preamp is replaced, that other stuff is just minor, and I REALLY love how the basses feel, sound and look. I'm still going to order more G&L's in the future, no doubt about that.
