double action truss rod, lightweight, hybrid titanium, 440mm length, ± 94 grams weight
This low weight, double action hybrid steel/titanium truss rod is an interesting alternative to a conventional truss rod system. The main advantage is the lower weight which will improve balance. Acoustic guitars are relatively neck-heavy; lowering the weight of a neck while maintaining adjustability is a key improvement. Using a lower weight truss rod (if possible combined with low weight tuners) might also improve on sound; a lighter weight neck will most likely feature a slightly faster attack and possibly a lower resonance frequency of the guitar.
As always with truss rods, we recommend to apply a lubricant on the threads before mounting it into the neck. Metal threads are susceptible to galling, a type of wear that can occur when fastening or disassembling threaded components. This might result in thread damage or seizing, which would be very difficult to repair.
