I've got a late 80's Ibanez RG 550 (japan) with an edge floyd rose temolo and the 2nd fret on the low E string buzz's like no other!!! I tried raising the action, shimming the nut, and changing the strings. Nothing worked. I thought to try adjusting the tention of the necks truss rod but it takes some sort of socket wrench (which I don't have) instead of the usual allen wrench. What should I do!
