In-house Service Centre: Guitars & PLEK

Our Guitar & PLEK Service Centre is constantly receiving guitars that need a little tender love and care and our employees are passionately doing their best detailed work on these axes. In this blog article we give you an inside peek of what goes on behind the doors. And if you’re wondering “What the heck is PLEK?” we’ll explain that too!

Leave it to the pros!

Whether your guitar is simply buzzing in a few spots or its action is so high that it’s unplayable, we’ve got you covered. Our Service Centre and Workshop workers are all guitarists and will understand your problem, no matter how small.

Tools we use

The number one tool used in the guitar service centre is the screwdriver, but sandpaper, hand files, chisels, hammers, vice grips, screw claps, string winders, drills, wood glue and super glue are all used almost daily. Then there are special machines like the PLEK machine (more on that below) and this homemade “pickup testing machine“:

What the heck is PLEK?

PLEK is a computer controlled system used to measure and adjust instruments – aligning frets and checking that neck curvature and string action match individual preferences. The PLEK Station is a machine that is manufactured by A+D Gitarrentechnologie GmbH in Berlin. There are currently 57 machines in the world and we’ve got one of them!

The probe measures the neck and frets of the instrument under full string tension (i.e. under real playing conditions) and from this, creates a profile.

The PLEK machine produces an evaluation from the probe in graphical form: on the computer screen you can see the difference between the ideal curve (green) and the actual position of the string (red) above each fret.

The computerized machine mills the frets with a precision of 1/100 millimetre to the desired height. Intonation problems are eliminated unless they result from a string action which is too high or low.

The result can be seen and heard: strings will not buzz against the fret.

Before the instrument is returned back to you, our guitar team polishes the frets, and adjusts the intonation and string height to your desired settings.

*In addition to electric and acoustic guitars and basses, PLEK works with mandolins, 6-stringed banjos and resonator guitars.
