Hardware zur Verbesserung der Stimmstabilität

Das patentierte Design des String Butlers wird am Kopf Ihrer Gitarre befestigt und korrigiert den Saitenwinkel.

Korrigiert die Position der A, D, G, H Saite zu einem gradlinigen Verlauf durch die Sattelkerben und verhindert so ein  Steckenbleiben der Gitarrensaiten im Sattel.

Outstandig seller & an excellent product. My String Butler arrived in Ohio in just 9 Days. In the short time I've had it installed my Les Paul Custom has had a better tuning stability than it has ever had before. Thanks Sven!

Hey Sven, I have the String Butler installed and I love it. There is a vast improvement to the tuning when I use my trem system. I will spread the word to my fellow musicians. I also run a guitar repair shop so I will recommend this to anyone with tuning issues. Thanks

Just fitted it to my Chord Legend 59, wow what a difference, superb, now stays in tune after bending, will be fitting on my other three guitars.

Awesome idea, just installed three on my SG's and LP.No more nut binding and the G actually stays in tune even after heavy bends...
