I am close to finishing my latest build, but need to do my fretboard still. I have a lovely piece of bocote (middle), a really interesting strip of zebrawood (right), and I though about using poplar to tone with the label on the box. Neck is black walnut.
I like the poplar most, from the color-theory perspective - but the zebrawood is amazing too.
(also, too: I'm seriously flirting with trying a bound fretboard on this one - trying to talk myself out of it, but I want to try one soooo baaaaadd....)
