defniitely so
i bought a fretless vmJ on here - the neck was fairly marked from roundwounds so i rubbed it down to remove the marks and changed it from a high gloss ebonol finish to a nice semi-matt which has more of the lustre of a piece of wood and looks more natural imho
see earlier threads [url="http://basschat.co.uk/topic/215668-ebonol-neck-cleaning-marks-off/page__p__2190999__hl__ebonol__fromsearch__1#entry2190999"]here[/url] and [url="http://basschat.co.uk/topic/203305-roundwound-scratches-on-fretless-ebonol"]here[/url]
the ebonol will mark with roundwounds but then so will rosewood - i think with the ebonol also it is down very much to your playing style - if you play fairly heavy with a pick then it will probably end up marking noticeably - if you play with fingers possibly less so - ive restrung mine with roundwound swingbass and no problems at all, some minor cosmetic marks on the neck but no deep gouges from the strings but then i am not a 'heavy' player and have a rather minimal/economical style so pressure is less of an issue - one thing that is a big no no with the ebonol is never bend the string as you would on a fretted bass or guitar, that will make a significant mark in the neck
also with the vmJ, i did try it with some black nylon flats to see how it would sound, the result was hardly any output! was very weak. as soon as i put some roundwounds on it began to sing beautifully, the seymour designed pups are quite big and have a failry meaty output for passive and respond very well to roundwounds and it produces this sort of tone quite nicely ...
