ABM has the best reputation for exclusive quality guitar parts, made in Germany (the reason I let them make my Dream Machine tremolos for me).
This is their version of the 'standard' Strat tremolo - standard in appearance but boutique quality in each detail, giving you the best Strat sound without any compromises!
