I'm looking at getting a 6-string lined fretless from a right-coast luthier. Right now the board is au-natural and he's wanting to know if I'd like the board epoxied. The problem is that I've never played a coated board so I have nothing to compare. Firstly, is there a noticeable difference in feel and what are they? Secondly, how about the differences in sound? I know there are a lot of other factors; strings, fingers, etc. but does anyone who has played both types have any knowlegeable positions on the matter? I will hopefully get a chance in two weeks to audition quite a few fretless' before I make a nod in either direction, but I'd like some other opinions..
