IME, the best mag combo for the BB Pros is the A3 neck, UOA5 bridge.
Lemonman, rounder, mellower & more woody is part of what I'm after (like Dickey Betts flutey sweetness). Do you recall if the bottom strings got "mushy" with the A2s?
Yeah, definitely not piano-like on the bass strings, but I can't really think of an A2 bucker I've used that I would call "tight" on the wound strings. It's one of the major reasons I've partially drifted away from A2 mags. Love the high strings, don't like the flabby low strings.
Part of the 'charm' of A2's. But, that's offset by other good qualities.
