One of my clients sent me this link. He's thinking of having me install a pair in the neck of one of his many P-basses. Anyone have experience with these (or something similar?). They should add stiffness without adding a lot of mass. https://k-t-s.com/en/pages/kts-neck-support-rods |

Titanium has essentially the same stiffness to weight ratio as steel or aluminum. That means that unless you can make the reinforcement bar taller, there is no advantage to using it as opposed to the other metals. Strength to weight ratio is where titanium excels, but this application is about stiffness (modulus of elasticity), not ultimate strength. |

+1 to John. Titanium's Young's modulus is not great. Aluminum 68GPa, titanium 116, uni carbon fiber 181, steel 200. Meanwhile the titanium is 4.6g/cm³ while carbon/epoxy is around 1.8. Unless you want to add mass for its own sake, carbon will be better. That said, I have always wanted to try a titanium truss rod, where its strength will really shine. Although there is a greater risk of thread galling than with steel. |

I have used carbon fiber for repair and mods of neck since the late 80's. I see the pro & cons of titanium, but wondered if anyone else had actual experience using it. |
