Excellent neck that fits my Reference perfectly. This is the third generation neck, which differs from the second generation only by the hinge mechanism. The new construction is slightly less massive, which gives a slightly improved response and tonal focus. Still, I returned the neck, as I found the difference with my 2nd gen too small. Also, while it did resolve some intonation problems, it gave some new ones in other registers. But all in all, if you have a broken neck or a first generation neck, I would say this replacement neck is the go-to solution.
