Can anyone shed some light as to why it's really only rosewood or ebony used for fingerboards? I know that certainly durability, denseness, etc. are characteristics of a good fingerboard.
I recently came across a board ft of cocobolo for pens and other various turnings. Once I got it planed I happened to set it next to my walnut banjo neck (same workbench) which is in need of a fingerboard, I got thinking that it'd look good fretted and inlayed. I can't find a supplier for bulk ebony in my area and am curious as to other options.
