What are Locking Tuning Machines for Guitar?

A locking machine head basically helps prevent guitar strings from loosening. These quality tuners employ a retaining or pin mechanism to ensure the string is locked in place. They can be adjusted by loosening or tightening a knob on the rear of the headstock. It has a clasp or clamp that surfaces upon tightening the button screw. This helps the string remain put or not slip away. If not anything else, it would at least ensure your guitar strings stay slightly more in tune. It may add minor heft to your guitar but that’s a very small price with these locking tuners you pay for better tuning stability and made from quality materials.

Are Locking Tuners Better?

There is a lot of debate about the effectiveness of locking guitar tuners over standard guitar tuners. String slippage is the best reason why they are a thing. A conventional guitar tuner that has a guitar string correctly wound around it and proper wrap positioning on the tuning peg should not face any string slippage problems. However, such a circumstance is not always the case.

Most guitarists invariably encounter poor tuning stability woes. Strings not in tune doesn’t necessarily mean the tuners are at fault. It’s imperative to ascertain the real reason(s) behind the bad tuning. However, these options for best locking tuners would certainly help fix an element or two that could have thrown the guitar strings off.

Can You Change Tuning with Locking Tuners?

As mentioned before, it isn’t the only thing helping a guitar keep its tune. Other major factors at play include temperature, instrument positioning, how forceful your playing style is, and the kind of strings you use. The locking tuners (such as one I haven’t mentioned yet – Schaller M6 or Kluson) or also known as a machine-head are also not going to help your guitars sound great or in tune at all times. There would be occasions when the guitar loses tune despite being equipped with one of these. However, unlike traditional non locking tuners, this gives you more control over how the strings enter tuner hole, get pulled, and lock. Not to mention, they also help save time locking strings in place.

Easy Installation Of Lock Tuners

Most of these are quite easy to install with no drill holes needed.  The entire process is to just place it in the headstock’s hole and put the collar over it and tighten the thumb screw.  No guitar shop needed.

Changing String Sets With These Locking Tuner Options

One of the main things that I love about these is that it is so much faster and easier to change strings.  As simple as just threading the string through the peg’s hole, locking it and tuning it up.  Cut off the excess string length and done!  String changes are way faster than a traditional tuner with less tuning problems!
