The return of Frankie 2I was never happy with this project as it was. The left-handed neck wasn't really working for me and the roller nut I'd installed made the action too high at the head end of the neck. Tonight, I replaced the neck for a more ordinary Stratocaster neck - a Squier Strat neck with 22-fret rosewood fingerbaord. I also removed the tremolo bridge, the springs, etc, and have installed one of these fab Hot Rod hardtail bridges from Custom Shop Parts. It now plays beautifully!
As for the parts that I removed, I may keep them for a future project or else I might have a clear out and sell them on eBay.
