View attachment 32417 View attachment 32418 What do I have here, (year-model)? The neck reads Fender Jazz Bass. made in usa. neck ser.# S7 37614. Neck plate: A big letter f and #277652. This bass has (mother of pearl?) fret markers and a rather nice white neck inlay around the fretboard. It now has twin vol. and twin tone pots. Under the pick guard, It looks like the pot cavity, (closest to bridge) has been bored out, to add the fourth pot. I'm thinking its a 77 jazz special. Am I wrong?
