A 13:1 Sperzell is a better and more accurate tuner than an18:1 or 20:1 Kluson, Gotoh, or Ping every day of the week because that is their emphasis.
I am definitely a Sperzell fanboy I have them on a lot of guitars especially my custom builds. However, my Klusons on my SG and 2 Les Pauls work great. Every time I think about changing them with locking tuners I ask myself, why? Still might do it if I can find a set for the right money. I have been looking at these Gotohs for a while, they have been sitting in my Amazon wishlist for a year.
