Hi Mike,
a friend has a 000-16GT built 2000 with "real wood" bridge (and fretboard,
as far as I know). My 000-16SGT is from 2004 with micarta.
If I didn't read about the change of material in some guitarrist forum, I
wouldn't know about it. The guitars sound slightly different, but that's
because they are different (14- vs. 12-fret). But I can't feel or hear any
disadvantage from micarta.
My personal opinion: If you like the sound (and you certainly will!) of the
guitar, then get it.
Best regards,
Juergen
