The bottom width is 55.5-56.5mm. The nut is 42mm wide. The tuner hole is 10mm. The string length is 25.5 inches. The fingerboard radius is 9.5 inches? The truss rod is working properly. The neck is very beautiful. I’m sure you’ll like it. It’s on sale now. Many dealers get their products from my factory, so the price is very cheap. I hope we can cooperate.
