Hipshot

The Tremsetter greatly improves guitar performance by automatically returning your full floating tremolo to an exact "zero" neutral position, eliminating flutter and sag, so your guitar remains in tune. You can bend strings, play bridge harmonics, aggressive rhythm parts or mute strings and the bridge remains stable. Best of all, the Trem-Setter is total retro-fit. No need to chop up your vintage axe, just install it and play!
