## Description

Traditional thumbscrew-style locking functionality with Gotoh technology.Pull the string taught through the tuner hole, and with a twist of the thumbwheel the string is locked into the post. Just a few turns of the tuner knob and you're up to pitch. Since there's just a partial wrap of string around the post, tuning stability is dramatically improved. Locking tuners are excellent for non-locking tremolo guitars, and for players that do heavy string-bending.Rock Solid™ string posts eliminate looseness and reduce backlash for improved tuning stability. No more wobbly string posts to cause tuning problems. Two post heights eliminate the need for string trees.The Lubri-Coat™ process electro-coats the gears with a special polymer layer. This eliminates the need for oil and keeps the lubrication where it's needed, for the life of the tuner.Gotoh SG381 MG-T16:1 ratio10mm (13/32") diameter pegholes required2 post heights: 18.5mm and 20mmRemovable metal knobsCosmo Black* finishThreaded hex bushings and mounting screws (6 each) includedSet of 6 in-line tuners*These tuners are available with Gotoh's translucent Cosmo black finish, a popular new alternative to standard solid-black plating.

Review: Gotoh quality with a simpler more intuitive lock than the MAG style - Exactly as expected...they are Gotoh locking tuners. Easy swap, well constructed, and function perfectly. Locking tuners aren't intended to enhance tuning stability, but the make string changes quick and easy. These are screw locking with a central post, not the Mag lock style, so they are less expensive than the common Gotoh lock style. They make an excellent upgrade for an Ibanez RG or S series in the middle of their price range. You will have to drill pilot holes for the tiny screw on the back, as these don't have the locking nubs the stock tuners use, so you will alter your headstock unless you are replacing screw in tuners to start with.
Review: If you want to take the hassle out of tuning a Floyd Rose, this is for you. - Do you hate fiddling with the fine tuners and locking nut on your Floyd Rose-equipped guitar? Then grab a phillips-head screwdriver and a set of these bad boys. Easy drop-ins on my JS32 King V. I love how the neck on my Jackson feels, I love the frets and I love dive bombs, but the Jackson branded locknut was a pain, so I grabbed a set of these, and with the addition of a non-Jackson Floyd Rose, my King V stays in tune better than ever, and when I lose tuning, it's easy to fix. Hate the fine tuners? Screw them flat and tune from the headstock. Helps you detune a floating Floyd Rose to Drop D quick, too. I also have a set of these for my ESP LTD MH in Chrome, and a 3x4 set on my Jackson DK2 Modern Ash FR7. Also makes string-changes a breeze. With a Floyd, I feed the string through the tuner, down to the saddles, and lock them in place, then pull the string taut, lock it at the tuner, tune up to pitch, then cut the ball end of the string at the top.

## Questions & Answers

**Q: Will this fit on a Jackson JS12?**
A: Yes they will fit, I looked at the Js12 Dinky. Remember three of the tuners in this set, have shorter posts, so you can remove 2 string trees. I used them and they work and look great. If you want the ones that are all equal length, check with the supplier, to make sure of which set to get. They are knowledgeable and friendly.

**Q: Fit fender strat**
A: The fit will depend upon the type of tuning pegs your guitar has.  Reach out to Stew-Mac.  They are very helpful.

**Q: Will these fit a jackson js32 rhoads left handed ?**
A: No not unless the guitar has a reverse headstock. These are for a standard right-handed guitar.

**Q: Will they fit on the Squier strat mini guitar?**
A: Please just check the back of the headstock of your guitar. If the current tuners have no screws you will need to drill holes for screws when you fit these tuners. If the current tuners have the screw on 45-degrees like these they'll fit straight on.

Fit the Wizard 3 neck on my Ibanez S521 perfectly without any drilling or mods. Great locking tuners. Love the gunmetal finish matches the rest of my hardware. Makes string changes so much easier. Recommended.
