L-2000's - I've owned 3 USA's and a Korean TRibute and also a pair of Asats with the same pickups/preamp. I love 'em! :wub:
I tend to leave mine in passive and in series. big growly,dark tone! The passive mode works without a battery as its true bypass and in either of the active mods the bass and treble are cut only.
the USAs normally ship with the #7 neck (12'' radius, 1.75" at the nut) but there are some around which would have been ordered with the #8 (1.5 nut, same radius) This jazz bass like neck is standard on the SB-2,JB-2 and Asat basses.
the tribute L2K's ship with the 1.75 nut width. there are no other neck options I believe on these. I used to own a lovely MIK L-2000. It was a natural ash/maple one and played beautifully.
Whereabouts are you,I'm in Ayrshire and if you're nearby you're more than welcome to try mine. I should also have my old L-1500 coming back to me as well sometime soon and that one has the wider neck.
cheers!
