## 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.

## 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.
