Best Locking Tuners - The Ultimate Guide

Best Locking Tuners - The Ultimate Guide

Get your guitar playing at its potential with the best locking tuners from Gotoh, Kluson, Sperzel, and many more!

More and more these days we’re seeing guitars come with locking tuners as standard. It used to be that you only really installed locking tuners if you had a tremolo, yet we’re seeing them on hardtail guitars like Telecasters and Tune-o-Matic equipped instruments like LPs.

As manufacturing costs come down, locking tuners become cheaper and thus more manufacturers start installing them on intermediate level instruments. This is great new for the discerning guitar player, many of whom may not be aware of the benefits that locking tuners can offer.

If you’re one of those guitar players then this article is for you. The best locking tuners enhance the performance of your guitar in many ways, from tuning stability, to quick string changes, to enhanced sustain. They’re simply a must have upgrade that will improve any guitar that they’re on! Let's get stuck into the nitty gritty

Locking Tuners: The Lowdown

Buying tuners can be a bit of minefield to negotiate if it’s your first time. From bushings to mounting screw locations, there’s a whole host of considerations you’ll need to take before purchasing and installing a new set of locking tuners. Thankfully for you, here at Northwest Guitars we’ve got bags of experience dealing with tuner installations, so follow our advice and you’ll get on just fine!

Tuner Hole Size

One of the most important things you’ll need to consider is your tuning hole size. Typically there are two tuner types, vintage and modern. Vintage tuners have a press-in bushing that holds the tuner in place whereas modern tuners utilise a threaded collar that’s tightened via a nut. Whilst they’re installed in slightly different ways, it’s actually the size of the tuning post hole that’s the differing factor.

Best Locking Tuners

Vintage tuners have a smaller, typically 8mm hole whereas modern tuners tend to use 10mm. This means if you’re converting from one to the other you’ll need to account for this. Changing from modern to vintage tuners is easy enough with a set of conversion bushings, however if you’re wanting to go the other way, you’ll need a reamer to make the hole bigger.

6-in-line vs 3x3

Headstocks typically fall into two configurations, 6-in-line or 3x3. The former was made famous by Fender, featuring on the vast majority of their instruments including the Telecaster, Stratocaster, P-Bass and Jazz Bass. The tight grouping of 6-in-line tuners means that they need to be a particular size to all fit together, as well as having the same orientation for all tuners.

3x3 tuners are famous for being used on Gibson and Epiphone guitars as well as their derivatives. Due to their arrangement on each side of the headstock, the tuners need to go in a certain order otherwise they won’t face the right way, a mistake that will quickly become apparent if you try to install 6-in-line tuners on a 3x3 headstock!

Mounting Screw Location

Mounting screw location varies greatly from guitar to guitar, so its vital to check this before making a purchase. Modern tuners tend to have one mounting screw whereas vintage tuners use two. On modern tuners the angle of the single mounting screw can also differ, sometimes sitting at 90 or 45 degrees from the tuner. Some locking tuners, like Sperzel’s have no mounting screw at all, relying on the attachment via the threaded collar at the front of the headstock.

If you can’t find a set that fits exactly, or you just want to change things up its fairly simple to drill a new hole. Just make sure to mark where you need to drill, use a drill bit slightly smaller than the screw, and wrap some tape around your drill bit at the same length as the screw so you don’t drill too far into the headstock! You can also fill the old hole using a tiny dowel or tooth pick to make sure no moisture gets inside your guitar.

Sperzel Trim Lok Locking Tuners

Famously used by Nile Rodgers, Sperzel Locking Tuners arrived in 1977 with a unique design that set them apart from the rest. Made in the USA, these tuners were one of the first instances of locking tuners being used commercially.

The Trim-Look system originated in 1983, quickly becoming the benchmark for all locking tuners. The thumbwheel design you see used on many locking tuners originated with Sperzel and it meant guitar players could do away with wrapping the strings around the posts, something that could cause issues with tuning stability.

With staggered string post heights Sperzel’s locking tuners help eliminate the need for using a string tree on guitars with flat headstocks. These six-in-line tuners are designed for fitting onto guitars with modern tuning machines.

Wilkinson EZ-Lok Locking Tuners

Well-known for brilliant offerings as budget prices, Wilkinson hardware is designed in the UK and manufactured in the Far East, resulting in ingenious solutions that are unbeatable value. The unique EZ-LOK system on these tuners sets them apart from others on the list.

Eschewing the typical thumbwheel design of a regular locking tuner, Wilkinson’s EZ-LOK system features 2 string post holes, 90 degrees from one another. When stringing you pull through the first hole, wrap 3/4 of the way around the post, then pull tight through the second hole.

Solid brass gears deliver excellent stability and precision, not that you’ll need to adjust much because they hold their tuning so well. The mounting hole is at 45 degrees so take care to make sure that aligns with those already on your instrument, or you’ll find yourself drilling and filling!

Kluson MLT33N Locking Tuners

Kluson used to be the standard for guitar tuners from the 1940s to the 1960s. You’ll often hear guitar players refer to tuners as ‘Kluson style’, because they were so prevalent on classic instruments. Sadly they closed shop in the 1980s, but have since re-emerged, revitalised at the turn of the century.

Kluson’s MLT33N Locking Tuners are another that doesn’t have the thumbwheel style locking action. Instead a small divot at the top of the string post provides the locking mechanism, requiring use of a screwdriver or coin to operate.

Sealed and self lubricating, these are high quality tuners a ratio of 1:18 for superb accuracy. A sophisticated clamp element ensures there’s no chance of them unlocking, even with the strongest vibrations.
