Re: Single coil Fishman Fluence modern output ??
Correct me if I'm wrong, but I don't believe there is a "Modern" Fluence in the single coil size, just the "single-width" models they've always had, correct?
If so, they are vintage-voiced and unlikely to give you the output you're after. The Blackouts single would be a slightly better option. However, going with an "active" pickup doesn't always mean "more output".
What is it about the Fast Track 2 that isn't doing it for you? The FT2 is the hottest single coil-sized pickup DiMarzio makes...makes me wonder if something is up with the wiring or maybe you haven't tried adjusting the pickup height?
