I hadn’t seen anything about this anywhere. Looks like it’s the Bogner Electronics ST-Pro. A pre-wired pick-guard with a set of programmable pickups, selector, and volume/tone/mode knobs. My opinion was the Strat and Les Paul modes sounded closer to their respective originals than did the Tele or hollowbody modes.
Yeah there’s definitely a place for this in a working situation. But you’re right about single point of failure and charging. You could buy two to have a backup, but at $1000 just for the kit … you can get a good enough guitar and a ToneX for that much.
