Schaller SureClaw

Sure Claw Sure Claw has been designed for guitarists who use a tremolo system with sustain block. It helps maintain the correct spring tension. The tension can be adjusted without removing the back cover plate. Always the same problems you could do without, such as: Using an extra long drill, drilling diagonally into the guitar body; Using a very long, special cross-recess screwdriver (and a lot of muscle) to unevenly screw in the two fixing screws; Running the risk of slipping with the screwdriver and damaging the guitar; Repeated, tedious removal and re-attachment of the spring compartment cover, just for the sake of readjusting the tension springs. All this can be avoided! Our patented Schaller spring tensioner (Sure Claw) is the solution: The Schaller spring tensioner is mounted horizontally and is easy to install (requires only two screws); Its worm gearing means that adjustment is child's play; Simultaneous, parallel adjustment of the spring claw; Closed tremolo spring cover
