The Breadwinner had an onboard preamp, too. Supposedly the first mass produced guitar with active electronics, I guess because Alembic are a custom shop. It was way ahead of it's time…after it was dropped from the line, the follow-up Ovation electrics (Preacher and Viper) were all passive.
While it had only one volume knob, there was an internal trimmer to balance the pickups to taste by offering boost and cut for the neck pickup. The tone control was a treble boost and cut, with a detent for flat response. The phase switch with another trimmer to fine tune how far out of phase it would be…that's bizarre. There is a switchable notch filter to reduce mids (why???). The pickup toggle is odd, too…neck, bridge and both out of phase (for that Strat "in between" sound) in that order. Maybe by adjusting the trimmer it's possible to get the pickups in phase (or at least close)? It took two 9V batteries for 18V power.
My college roommate had both a Viper and an Ovation flattop guitar. His whole family played both guitar and banjo and would have weekly picking sessions with James Rickard who was the engineering manager at Ovation. He would drop off prototypes for them to try out, so Tom got both of those guitars plus an Iida banjo (MIJ, imported by Ovation) as freebies. That Viper was a great guitar, build quality was top notch. It sounded like a Telecaster with really hot pickups.
