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.

• 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 allows problem-free readjustment using an Allen key
• The Schaller Sure Claw has three cavities for the tremolo springs, which means you can use up to three springs when you need to.
