Marc Terreur - Understanding Guitars bloggerHi. My name is Marc Terreur but some call me Marcus – feel free to use either. I’m a Belgian luthier and my company is called Marcus Guitars & Basses. If you’re interested, you can see some of my work at

Another great passion in my life, besides guitars, is writing. I totally love language and am fascinated by it. Consequently, my decision to start a blog didn’t come as a surprise to those who know me well.

It goes without saying that a writer should be familiar with his subject. If he wants to teach about it, he should be an expert. The following will hopefully assure you that I’m entitled to write about understanding guitars.


  • I play the guitar since age 10 or 11, took up the electric bass a few years later. Many other instruments followed: banjo, mandolin, ukulele, lap steel, upright bass… They’re all different, but on the other hand they’re all members of the same family. Their strings vibrate alike.
  • I’ve studied math and sciences in high school, and I must say: having some understanding of physics turned out to be beneficial. You’ll notice that in my articles from time to time.
    (I won’t be able to put my Master in Sociology to much use, though.)
  • Since my mid-teens I’ve been customizing my own instruments. We didn’t have internet in the 70s and books on the subject were scarce, so my first efforts involved a lot of trial-and-error. I learned a lot that way.
  • In 1992 I discovered that a School of Lutherie had been founded, only a 45 minute drive away from my home. I took classes there from 1992 to 1996, and I have been building custom electric guitars and basses ever since.
  • I turned professional in 1995. In those starting years (to make ends meet) I worked for 4 different stores. Nowadays I only work independently, since I prefer being my own boss. But the biggest music store in Belgium still sends its customers to me, whenever their guitars need some serious repair.
  • In the past I have been writing guitar tech columns and instrument reviews in 2 Belgian music magazines. That was fun to do!
  • Over the years I appear to have built a solid reputation, but I did so without advertising. The positive reviews I got in different guitar magazines (foreign and domestic) may have helped a bit, but I know for a fact that word of mouth did most of the work for me.
    Although there may be guitar techs nearer to their homes, customers come to my workshop from all over Belgium, some from Holland. Often, one setup is enough to convince them to bring in all their other guitars as well. I cannot begin to count the number of guitars that have passed through my shop.


Now the time has come for me to share some things with you. I hope you’ll find them helpful.
