A white plastic bridge pin with a black dot, sold singly, for steel-string acoustic guitars. The plain one-piece pin that most factory acoustics ship with: it pulls straight up out of the bridge at string-change time and pushes back in over the ball end. Handy when one has cracked or gone missing, or buy six to replace a mismatched set. Match the taper to your old pin before fitting. AMS part number GP310W.
