Hate to disagree with you but most of it is dyed. Even the $8000 M8M is very light rosewood dyed black.
5000 series
All this stuff is dyed. I don't remember how many years ago it started and which models but it's been a while now. That's why I don't scrub down a fretboard with steel wool after edge, fret, and end work to smooth it all out. ooops.
You know when it's not dyed, it's not pure color. PIA's and JS's never dyed and sometimes you'll get lucky and get that great piece of ultra dark with no pores, but they're uncommon. It's extremely good rosewood but the choice AAAAA stuff is an accident.
Isn't the 5000 series m. ebony?
I count the M8M as something of a "limited", but I suppose when the limit is "as many as you order" it doesn't count.
