Everybody loves the sound and feel of new guitar strings, but they go out of tune so fast. Veteran guitar players and techs know that you have to stretch the strings to break them in, but doing it manually takes so long.
That was before this simple device that will stretch your strings so quickly and easily that you'll wonder why no one ever thought of it before. It's called String Strecha.
String Strecha is a device that cups under the strings and allows you to give them a pull in one short motion. It will allow you to stretch each string by the same amount every time, so there's no over-stretching if you follow the instructions (see the video below).
This thing is a favorite of top-flight guitar techs everywhere, and you should have one in your guitar case or in the studio at all times.
It's only $14.95, but you can get a couple bucks off on here on Amazon.

Seriously, this is my favorite new studio tool!
