Super-Vee Mag-Lok Tremolo Anti-Deflection Device
Item: VEMAGLOK
If you love your Strat tremolo but hate the de-tuning that bending one string causes for the other strings, you will definitely love the Super-Vee Mag-Lok. The Mag-Lok's patented design allows you to use your whammy bar, but when you are not using it, it "loks" the tremolo bridge with a magnet and your strings will stay in tune while you bend.
The Supr-Vee Mag-Lok is a simple, ingenious device that works. It will fit almost all Strat and Strat clone tremolo units and is quick and easy to install.
