Re: Grover Locking Tuners
Did you read the instructions that came with them? You need to turn the post by hand until it clicks, then turn the tuning peg in the loosening direction until the hole is pointing towards 5:00 (imagine the tuning post as the face of a clock.) Thn pull the string as tight as you can and tune. As you turn the peg, the lock in the hole will tighten and grab the string. Tune to pitch, stretch your strings, and you're ready to go.
