The Headstock Tuner came with
"The Headstock Tuner came with no instructions. I’m a 74 yo trying to be young again and I would like to know what the frequency setting is for. I would like to experiment. I have a 60s les paul standard faded, which I already changed the pick ups for a Burstbucker Pro. I’m trying to adjust the action and changed the strings for softer ones but the high E broke so I’m waiting until is in stock again. I was able to use the tuner and was successful, thank you."
