Nah, I think you are right... at least about some of this. I know there are some mass produced Nordstrand pickups made overseas, as well.
I guess I'd like to know if Jimmy actually makes his preamps, or like Carey, designed it and maybe prototyped it, but still has them made elsewhere for stock. If you wanna' get real detailed, I'd ask if his preamp is PCB based, and if he actually has PCB etching equipment.
Not a big deal at all, but it is kinda' interesting, because at least for the lion's share of Jimmy's instruments, I doubt there are many others in the world doing as much directly as he does (getting back to the OP on this), so the point stands.
