That's the first I've heard of Brubakers being so called "modern". They certainly don't sound like stereotypical boutique instruments IMO IME. As with anything, it's helps to actually check out a few. Mine have a wide range of tones, including traditional, at my fingertips.
Good to see Wal up again.
Yeah, I was definitely generalizing, not having played most of those instruments I don't know exactly what tones they are or aren't capable of, just the impression I get when I look at them. As a mainly passive bass rock'n'roll dude, Wal's are one of the only "fancy" boutique builders doing these kinds of builds (as opposed to high-end Fender-style basses like Sadowsky, Alleva-Coppolo) - that appeals to me. Some Alembic designs come close, but the Wal takes the cake in my eyes, for whatever reason. I can't afford one, but if it were within my reach, I'd love to have one in the stable.
