I am looking at buying a neck through unfinished project bass. It is routed for electronics, the neck is already fretted. He is unsure of the scale length. To check would I just have him measure from where the nut will go to the 12th fret and multiply by 2? By the way, it isn't the builder selling, I would hope the builder would know the scale length. This is just the body/fretted neck with tuners. Routed for electronics. If it turns out to be 34" scale and I buy it I will be sure to post pics of the completion process.
