GOTOH Guitar Pegs, Rotomatic Type, Magnum Lock Trad with 01 Button, 3+3, Chrome (07202CYTX) SG381-MG-T-01-3+3-C These are Gotoh Magnum Lock pegs. For use on the left and right sides. For Gibson, Epiphone, and other guitars with a 3+3 headstock. I wasn't very interested in them, but I haven't used these because the size didn't fit. However, the Magnum Lock is amazing. I was having trouble with tuning on a guitar with a Bigsby, but this solved it all at once. If you're interested, please consider them.
