SuperVee's Maglok is an anti-deflection device designed to keep your guitar in tune while using your tremolo to its fullest potential. Our anti-deflection tool is easily installed to your BladeRunner or Maverick tremolo with a single screw and phillips head screwdriver. The revolutionary design behind the Maglok incorporates Rare Earth super magnets to resist detuning during hard bends and eliminates string sag. Offered in two pull strengths, the Black Edition is a great choice for Strats and Strat-like guitars, while the Gold Edition offers 25% more stabilizing force. You'll notice a dramatic improvement in tuning stability across stock bridges, Floyd Rose, Vega Trem, and Fender trem systems.
