Hi there-- Very little info online about the value drop of an instrument with a replaced fingerboard. Found a thread here that touched on the subject, but it was established that the board was just planed for a refret and so was never fully addressed. So... On a vintage P Bass, what would you say the value decreases by if the fingerboard has been replaced? Where would you put FMV on a 3tsb very road-worn, but otherwise original, 1970 P Bass with ohsc in this predicament? Thanks much.
