Grover V97-18N Sta-Tite Machine Head

clearly a better grade tuner than standard issue . the holes left don't quite match up with the Grover's but a very , very small bit and a very shallow hole get you off and running . no big deal . definate upgrade . Again , prompt service , great communication from Thomann . Thomann is gold ( wish I had more $$ to spend with them ) . Someday a National .

I bought this product to replace my guitar tuning heads, and definitely is and absolute upgrading to my guitar.
the tuners are solid and so far keep the guitar tuned most the time.
Will se what happen in winter and string naturally contract by cold. But so far now I am pleased with the product.
