Schaller Tremolo spring tensioner (Sure Claw)

You have a tremolo and want to mount the spring plate in the guitar body?


You want to readjust the tension springs and have to completely remove the spring compartment cover again?







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 allows problem-free readjustment using an Allen key

Wonderfully simple, and simply wonderful!

Give it a try.

A spike for center-punching the cover is included as an accessory.

Simply place this spike in the Allen socket on the adjustment unit, then put the cover into place so that it is marked by the spike. This shows you exactly where the cover needs to be drilled, which means you can then make adjustments without having to remove the cover, simply by inserting the Allen wrench through the hole.
