This is another good quality, affordable guitar accessory from Musiclily. The bridge is one way rather than two way – meaning the pitch of the strings can be lowered but not raised as with two way. One way tremolos are easier to set up and in my experience hold the tuning better than two way.The block is good quality – solid brass – and the fixings, including springs, are all included. The tremolo arm is the push-in type rather than screw in, which means a small hex grub screw must be lightly tightened (hex key included) to prevent the arm from dropping out.The bridge is designed to fit a standard Fender Strat or Squier Strat, and is available in three finishes – black, chrome or gold.The quality and function appear equal to the Squier model bridge, so although it may not be necessarily an upgrade it will certainly serve as an affordable customising project if a colour change, or swap from a screw-in to push-in arm is required.
