(Update 05/09/2012): The Stay Toon’d tremolo Claw can be purchased from this online store.
It seems guitar innovations are mostly coming from digital technologies these days. However, no chip is going to keep your Stratocaster in tune if you Hendrix the hell out of its tremolo system (I think Hendrix can be used as a verb, don’t you think?).
Scott Lionello is a young Canadian who’s come up with an original solution to Stratocaster tuning issues. And it’s not a new type or nut or saddle but it’s a replacement “spring holding” system. I am talking about the springs in the cavity underneath the tremolo system. The idea is that the claw keeps the springs immobile when the tremolo is not used thus improving general tuning stability. It also improves on the “smoothness” of the use of the tremolo.
A video is probably better than a written explanation: here is Scott showing how to install the “claw”. Towards the end, you can see how well it keeps Scott’s Strat in tune, can’t wait to try mine! Note that there is a USPTO provisional patent on the Stay Toon’d Tremolo Claw.
Never buy this stuff! Today half of the day with the master tried to install on Suhr Modern pro M8. Holes for supporting screws are not the same – had to expand, spring fall when working the lever up, and then another, this very Tremolo Claw stood at an angle and it was impossible to close the back cover! This developer Van Rosa – conman. Wasted money and a bunch of nerves!
