I am just returning to the bass after a nearly 20 year break. I have a 1978 fretless P bass neck on a J bass body (year unknown). The neck probably doesn't have 5 hours of playing on it, just a few small chips in the varnish from bumping a chair. I would like to have some more dots put on the top of the neck so I can more easily figure where my stiff fingers go. I might even just use a sharpie marking pen. Looking for a paper scale so I can figure out where the dots or marking pen goes. The local music store doesn't want me to pull out a tape measure. Any help wil be appreciated.
