Expected quality from Kulson.
Used to replace some standard tuners and it does lock my strings. not the first pair of this same system of tuners.
Pretty easy to mount. Now days, pretty much all guitars share the same diameter on the holes for the machine heads on the headstock, so Im 99,9% confident if you have an ST type guitar, this will fit on yours. From Harley Benton ST 62, 70 to Squier Affinity, Pacifica etc.
The gold color just give the headstock that "suave" vibe.
