Oooooh! That'll be a fun bass! Congrats in advance!Mine was built in 2012 and is on the way to me. The layout is different. It has the switch so it must be a ZB-4.3. Although the build sheet says 4.3. Dosen't have stacked knobs.
Is be very surprised if it isn't the same controls as the 4.3 from my previous reply, just with the bass and treble separated into single knobs, bass towards the neck, treble towards the bridge, with mids in the middle. If you find out otherwise please share!
