<p>Grover's Perfect Guitar Nut Height Extender takes your existing guitar and adds slide steel sound and playability by raising string action by 3/8". Just install the Perfect extender over your existing nut, replace the strings, grab a slide, and go! You'll have so much fun discovering the new sounds you get out of your favorite guitars, you'll love them even more. And since it's a temporary installation, you can move it back and forth between your electric solid body guitars and your acoustic guitars for even more tonal variety.</p>
