Incidentally, I have just found out why the high B and E-Strings on my HotRod Strat were buzzing like a sitar, the cause is definitely the Chrome Schaller R2 Locking nut, so I'm definitely replacing it with a Gotoh Locking Nut for sure, I've temporarily installed the Black Gotoh Locking nut that was on my white Ibanez RG350DXZ guitar.
