I have an AB1, the B string (37") has way more tension on it than a normal 34" or 35" scale bass. So I don't see how the B being 35" will get that high tension which focuses the sound of the B string, takes the flop out and allows you to dig in on it just like any other string on the bass.
So maybe there is some benefit, but not the maximum benefit I would say.
Like another TB'er already said, the Super J/ P series is 35-32" scale. You get the benefit or a slightly-longer scale B with a shorter than normal scale on the G.
While 37" gives you the ultimate B (ABZ5 owner here), I think that 35" is a lot more appealing to 'traditionalists' (term used loosely; we're still talking about dudes playing fanned frets). And any extra scale length works to improve the low B. IMO, 35" is perfect for the Super-series, since they're based on old-school designs.
I'd love to try one of these new Brice's out, even if I am perfectly content with my ABZ5. I'm sure it's not even close to Combustion quality, but we're talking several hundred dollars difference. I'm curious as to their ergonomics (it is very similar to Dingwall in shape). I'm not big on the extended fingerboard nearly touching the neck pickup, but some quick Dremel or chisel work would take care of that.
And for anyone questioning Brice quality, it appears that Brice is just the bass-equivilant to Agile. Just Google "Agile" or take a look at extended range guitar forums. Rondo wouldn't have so many 7+ string model guitars in the Agile range if nobody was buying them.
My wallet is hoping they don't put up a fanned fret 4. And now I'm thinking the 5, defretted, would basically complete my bass lineup
