11 reviews Write a Review


Guitar and Bass tuning machines are sold by the side of the headstock they are mounted when viewing from the front. Left or Right side is not the same as left or right handed. Please remember this when placing your order.

  • GOTOH SG381-07-MGT Locking Tuning Machines
  • Sold Individual for replacements and for custom post configurations
  • Small metal knob
  • 16:1 tuning ratio
  • 45 degree offset mounting hole (the mounting hole is located 45 degrees from the vertical center of the string post)
  • Available in 3 string posts lengths (Short, Long, and Ex-Long) for creating staggered post heights
  • ROCK-SOLID posts prevent the rocking of string post
  • LUBRI-PLATE lubrication for smooth action and longer life
  • NEW MAGNUM-TRAD Traditional style locking tuner with thumbwheel
  • Includes bushing and mounting screw

The GOTOH MG-T uses an intuitive rear mounted thumbwheel locking mechanism for fast string changes.

Available in 3 string posts heights for creating a staggered string post arrangement that will give better tuning stability and increased pressure at the nut for better tone. Most guitars with the standard 3 x 3 configurations will use the standard 20mm long posts. Guitars with inline tuning configuration will 3 - 20mm long and 3 - 18.5mm short posts.  Please double check your headstock thickness since some guitars with thicker headstocks, like ESP/LTD guitars with inline tuning machines, will require 3 - 21.5mm Ex Long and 3 - 20mm long posts. The 18.5mm posts can be installed on a headstock with the maximum thickness of 14.2mm (9/16").

**The maximum string diameter that the MG-T can except is 1.8mm or (.070"). This should be considered if you are installing them on an 8 string guitar with heavy bottom strings.

Locking tuning machines will use a shorter post than non-locking tuning machines. The string posts are on average about 1/16" (2-3mm) shorter so you will have the proper downward pressure at the nut and increased tuning stability.

    It came pretty quickly and it was a totally reasonable price. I'd buy from here again.

    Just what I needed

    Posted by Paul L on Oct 21, 2020

    I needed a certain length post for my tuners, and there was no finding them at the popular online stores. Being able to order exactly what I wanted from Philly (and at a great price) was exactly what I needed.

    Got a couple of sets to replace some old and worn out tuners. Great tuners fixed all issues. Even stability issues with a Floyd Rose system. Highly recommend

    So great to have these!

    First of all, huge thanks to Philadelphia Luthier Tools for their quick shipping. I purchased these Gotoh locking tuners with the extra long posts version which are incredibly hard to get. Almost everywhere has the staggered version ONLY which just wasnt going to work for my project, I looked and looked but just couldnt find anyone who sold all 6 tuners let alone a custom number of them with different customized post heights, luckily Philadelphia Luthier Tools had them and even better at a very well price. Now I can complete my project!

    Excellent replacement tuners. Make sure you verify headstock thickness as these come as a staggered set.

    I received six of these Gotoh tuning machines yesterday and installed them today. They look and work great! A special thanks to Kenny for his excellent Customer Service by assisting me with exactly which of these would work on my guitar. I highly recommend these locking tuners and this store for all of your guitar needs!
