[quote name='mattbass6' post='622357' date='Oct 10 2009, 11:55 AM']Thank you so much. I understand that with any bass, depending on woods and construction, sounds will vary but I wanted to find out the general opinion on Barts.[/quote]
Matt,
I've got Bartolinis in both my Zons and, to my ears, they're really growly & (IMO) have a sound that's really suited for the sort of music you play - not sterile & hi-fi sounding like many active pickup/preamp combinations but with much more bite & definition than a passive pickup.
My basses have both got the stock Polyfusion circuits (9 volt in the fretless & 18 volt in the fretted) & I find these circuits to have a warmth to them I've not heard in other active circuits.
Personally I think they're the best bass pickups you can get, but as you know this stuff is really subjective.
(Having said all that, I think the Zon pickups are custom models made especially for Zon, so I don't know how these differ from standard Bartolinis).
