These fine reproductions feature old style stamped gear housings, but have modern improved 15:1 gearing for smoother, more precise action. The "scalloped" knobs are the same as found on many vintage Martin and Gibson acoustic guitars.
All sets include mounting screws and press-fit peghead bushings. 11/32"-diameter pegholes required.
To be sure these tuners fit your instrument, compare your existing machines and peghole dimensions to our listed specs to help determine the best replacement.
