I'm starting to build my first bass It is going to be fretless. The initial plan was to use ebony for the fingerboard, but due to limited supply I'm thinking about other alternatives. What about (Khaya) mahogany? As long as it would be coated with epoxy there should be no problems with wear, right? I'm digging the looks of it, other choices are wenge and padouk. I assume mahogany would produce a bit warmer sound compared to ebony or wenge? Otherwise it will be singlecut with one piece through-body maple neck and walnut body wings. Here's a rough example to see how it should look like.
