I did a little searching but didn't find much info. Most of it was from a few years ago. Seems like they are perpetually out of stock at allparts/bassparts, they show up sometimes in eBay... are they all going straight to Fender to go on their factory-installed models? Are they just not able to keep up with demand? I see Fender occasionally using its own BA style High Mass bridge. I emailed Leo Quan a long time ago but never heard back. How about the alternatives out there, anyone done A/B/C with the BAII and Gotoh etc?
