I was on hold with a retailer and the recorded message was pushing fretboard conditioner. I recently picked up a Highway One P with a rosewood fretboard (love it!). Previously I only used Ricks with their glossy finished neck or a fretless roadster with a satin maple, not un-treated rosewood, with is probably what attracted me too it. My 3/4 has a rosewood fingerboard and I've never done a thing to it. Am I supposed to care for it in some way besides the normal wipe-down?
