I finally got some vacation time, and I'm staying at home, so when I was out running errands today, I took my Chadwick's end pin with me and made a stop at the local woodworking specialty store. I found that the Glasser Carbon Fiber end pin that came with my bass had a twist-lock on it that would accommodate a 3/8 inch dowel. So I picked dowels up of cherry, oak and black walnut. When I tried them in the bass, I preferred the walnut, which is not surprising due to the Traeger book I read reporting that give a lot more volume and tone. My daughter agreed with what I thought of the switches, too. Cherry seemed a bit tighter, but still pretty full sounding. I do have a question for others who have tried this. Have you tried turning a full, plug-sized end pin out of a wood you liked, and if so, did you like the results, or not?
