Seems like they've gone to 38mm nut widths (1.5 inches) on some of their newer basses, which were previously 42 mm. Damn. I liked their longscales with the 42mm nut. Guess if I want one with 42mm, I'll have to look around for used. I like the old RBX170 (they don't make those anymore). It has 42mm nut. (Actually measures 1 and 5/8ths inches). Was hoping I could find one exactly the same but with the onboard active EQ.
