The truss rod is working properly. Nice neck. I'm sure you'll like it. It's on sale now, thank you! The necks on these guitars are gorgeous. Sell at wholesale price. Many suppliers get their products from my factory, so my prices are cheaper. Thank you. If you believe me, just buy once. I'm sure you'll like it, and I'm sure you'll be a repeat buyer. Because my guitar neck is a tough quality product. I hope we can cooperate with each other. thank you
