    Graph Tech Nut

    Replacing the stock nut with a graph tech is a good way of increasing tone/sustain and helping reduce string breakages. A great product that is easily fitted and great value, VERY HIGHLY RECOMMENDED.

    Super finish, stable tuning.

    This nut is an excellent upgrade for Jackson JS22 models. The 2-point trem have a hard time staying in tune with the extreme path to the machine heads. I did have to use a 0.020" veneer shim on the bass side. No other trimming was necessary. I also fitted locking tuners and since fitting the Tusq nut the tuning is very stable with normal trem use. Well worth the cost.
