​

You might ask yourself “Why should I go to a Plek center, rather than my local guitar tech?”

 

To which we would say: Having a good guitar tech on hand is a wonderful thing. If you’re happy with your guitar tech, then by all means stick with him or her.

 

But a good guitar tech equipped with a Plek machine is a killer combination.

 

For guitar techs, a Plek machine is a tool that can take their skills to a whole new level, taking a lot of the effort out of fret work and raising the bar in terms of exactness and quality control.

 

For you, the guitar player, having your guitar Pleked means that you can not only feel the improvements, you can also see the difference. In addition, you have a record of before and after. And you can repeat exactly that setup on a different guitar or again on the same instrument whenever additional work needs to be done.

​

What can PLEK do for my instrument?

​

Whatever your playing abilities, if you are serious about your playing it is worth asking yourself the question:
Is my instrument as good as it could be?

 

And if the answer to that question is not a resounding “yes”, then we might be able to help.

 

Over the years, we at Plek have devised a way of measuring the curvature of the neck – known as neck relief – as well as the height and relief of the frets and the fret radius over the entire neck, all in microscopic detail.

 

What are typical signs that my guitar needs help?

 

There are a number of tell-tale, give-away signs that your guitar is in need of help. These may be any of the following:

 

• Buzz areas on the fingerboard

• Fret wear, uneven fret heights

• Uneven fingerboard

• Action is too high/too low for my playing style

• Fret-Out: String tone dies away during bending due to unwanted contact with a fret.

 

In general, if any of these issues apply, we can say that your instrument basically has poor playability due to a setup problem.
