Gotoh SD91-05M-HAPM Locking/Height Adjustable Posts, Vintage Oval Knob, 6-In-Line Tuners

6-in-line locking tuners that are the perfect upgrade for old or new Fenders with "Kluson-style" tuners — they're a great retrofit

These fine reproductions feature old style stamped gear housings, but have modern improved 1:15 gearing for smoother, more precise action.

All sets include mounting screws and round press-fit peghead bushings. Peghole spacing is 4-11/16" (119.06mm). 11/32" (8.73mm)-diameter pegholes required. Please note that 3 of the tuners have a green decal on the back of the machine. These 3 machines have a smaller diameter string hole, and are to be used with the unwound (G,B,E) strings.

The locking mechanism works by inserting the string through the hole in the post as per usual but making sure that you hold the end of the string taught while turning the tuning machine button and this will automatically clamp the string into place. Once the string is locked, simply continue to tune to pitch and you won't need to wrap the string around the post more than once. The advantage of such a discreet locking mechanism, without the usual large locking wheel at the back of the tuner, is that it retains the vintage look of your headstock but with the added advantage of having the solid stability of a locking tuner. When it comes to string changing, simply detune the old string and use a flat head screw driver or a coin in the slot at the top of the post to undo the locking post which will in turn release the string.
