I used to have Schaller's for years in my strat, Its almost a year now I've changed to Gotoh's. Good Tuning Stability both for the string and the tuner itself, its well constructed and not wobbly even without strings. I ve closed the past season with 132 gigs, in which I restring my guitar in almost every show. I love the way vintage tuners "lock" the string. Great for the price, way more than I expected. I definitely recommend them !
