I used to have fine tuners on all 4 strings because I had trouble turning the pegs, which I used peg drops on because they were slipping. The other day I took my pegs one-by-one and cleaned the peg drops off with alcohol, let it dry, and sparingly put a new product I found called “dope”. Dope looks like a tube of dark brown lipstick. I put a little on and turned the pegs about 10 times to spread it good. They were still a bit slippery at first, but I guess it set in because they are perfect now. I love the sound now. Just a fine tuner on the e-string now.
