Re: Do fretboard woods really matter that much?
I find fretboard wood makes a difference as one part total of tone balance.
I use SD Distortion pickups and in my ebony fretboard, the pickup tone is bright already and the ebony is bright, so it's bright on bright. It works, but the Distortion paired with my rosewood fretboard, it's bright pickup on a warm and spongy sounding surface. When you have that tonal balance, you get what the tonal chart says about 'works especially well with rosewood' or 'works especially well with ebony or maple'.
So, you can place whatever wherever, it's just you get more tonal spectrum of sound which can result in some pleasing results. The charts REALLY help, but aren't rule.
