I saw a couple 1985 Jackson customShop units on ebay early this year and got super jealous, then mad cause they wanted WAY WAY too much for a used unit, so I outdid the customshop verision...let me explain in pictures:
in 85/86 it was a popular option to get a model 1 or 2 with a p/hb:
so yes I can play righty basses flipped, but the used cost is way too high obviously or I would own one by now....so since I have the same thing as the pic above, just in lefty and a b.o. neck:
I tuned it into this and added my spare Kahler until I find a black one:
talk about a tonal difference from OEM p/j, and I sport it on stage as much as I can!!!
.
I wasn't expecting someone to take a pic..sorry for the "wow does this guy look wasted" picture...( because I was )
my next mod is to pull one of the preamps out of my other C/J basses, and make the lefty active, and perhaps add one more switch to coilsplit the HB. Because I play inverted, the E string is on the pickup closer to the neck like a Fender is, and it does make a difference for sure
