The ABM 5050-M Tremolo System has the string and pivot screw hole spacing of Fender Mexican Standard Stratocasters with a chrome plated steel base plate and vintage style nickel plated bent sheet steel saddles, giving you the look and feel of a six pivot screw system but with modern upgrades. The cold rolled steel saddles are more precisely shaped around the height adjustment screws and so the screws are supported all the way down, this means shorter height adjustment screws can be used making it more comfortable on the hand and more stable. The steel base plate and hardened pivot screws ensure strong and hardwearing knife edges and the 5050-M tremolo also features a solid steel sustain block. The tension holding the tremolo arm can be adjusted via a set screw in the bridge and the arm and all mounting hardware is included.
