Thanks for the kind words, y'all! I was mentally prepared to have it not come out 100% straight, since measuring on an arch top with so many curves is not easy. I suppose though that maybe I've drooled over enough photos of vintage dual-Bisonic Starfires over the years to have a good template in my head. To be completely honest, the original factory Bisonic is mounted ever so slightly on a tilt.. hardly noticeable, but that makes my bridge pickup installation straighter than factory original
MAV, I would love to have a bass with those Alembic pickups, but I don't think there's anything my ears like more than a vintage spec Bisonic. Kinda like the old Gibson mudbuckers (but completely different of course), I think they're great in their own light and could see liking them in certain settings, but first and foremost I pledge allegiance to the ol' Haggies.
HAPPY, this bass came from a friend of mine who owned it for a long time as a backup to his '68 SFB-II. His original intention was to hotrod it with another pickup and passive mid-notch filters, but he never got around to it and his SFB-II never failed him, so this one spent most of its life in the case; which is also why it's in such clean shape. It was passed on to me a little over a year ago for a very fair price, as my buddy wanted it to go to someone who would really appreciate it and play it (bonus points for a fellow Airplane/Casady fanatic).
Aside from all this, it is a bit of a rare bird as it's a transitional model with both the bigger headstock design introduced in 1970(?) and a Bisonic, which gradually started to be phased out roughly around the same time. And of course it's an absolute gem in terms of playability, resonance, and so on.
