Is their current 6 string neck still NOT thinner in the treble side than the bass side? That is something I love about my bb75 and yet I recall the 76 not having that feature.
I ask because if the 6 isn't thinner on treble side then that's another BIG feature I'm looking for in a six string....
The existing 6 is more uniform (not asymmetrical like your BB), with noticeable (to me) squared-off 'shoulders', so that the back of the neck seems flatter. Personally, I've tried it and do not care for it at all.
I would be hoping for a little more of Brian's design magic to create new profile altogether...
