The USA-made Ultralites are reversible so they'll fit either side, the cheaper Licensed ones aren't (as far as Hipshot say anyway, I think people have managed to reverse them, but I don't know the process). So whether in-line or 2x2, you should only need to reverse one tuner. I haven't done it myself yet, but if I like the SS Ray I'll be getting USA Ultralites, they're the best tuners I've used.
I'd wait for Voyevoda to confirm before ordering, but I believe I saw elsewhere that 1/2" post Ultralites fit these basses.
