I"ve tried once on here but i"m gonna try again as its driving me mad. I Recently got a yamaha BBN4 bass and the serial number dates it to dec 06. All the other pics online of bbn4"s have the 2 either side tuner configuration and i"ve yet to see one with the 3 & 1 configuration ( which mine has ) the closest answer i"ve had is that yamaha were given a warning by Ernie Ball regarding the 3 & 1 configuration as they hold the copyright for that headstock configuration which is why yamaha went on to use the 2 either side, whether this is true or not i dont know. Considering the bass is only 3 years old they seem to have faded into oblivion and i cant find anything anywhere. Is there anyone on here that has owned one of these basses or still own one that can shed some light on the subject. Mines the natural colour with the jazz pickups, great sounding bass and light as well so no backache.
