The String Jack is for the adventurous guitarist who wants to explore a different approach to string bending.
Also explore the uncharted territory of extreme string bending on the acoustic guitar. It's like bending the strings behind the nut. Simply position a String Jack(s) under the strings, find a tuning and the rest is up to your imagination.
A single String Jack can span 2, 3 or 4 strings and can be placed in any combination on top of the fretboard. Jack up all the strings and you got yourself a Koto. The possibilities are endless!
