In-house Service Centre: Strings

Our Strings Service Centre department is an interesting dive into history and delicate instrument gems from musicians of all levels. We present to you a short blog article about our Service Centre: Strings department ?️? at the Thomann headquarters in Treppendorf.  Enjoy!

Leave it to the experts!

String instruments can be very delicate, and extremely expensive if they are passed down from  generations who have taken good care of them. This is what separates string instruments from other categories, their delicateness inspires a unique sense of respect for the instrument. That being said, yes, Thomann’s String Service Centre department does also fix and maintain instruments that were not bought at Thomann. The department often temporarily houses instruments that are hundreds of years old, including this cello from Cremona, Italy pictured below:

So having the right tools and expertise is essential to keeping a string instrument in playable shape, whether it’s a violin, viola, cello or doublebass (also known as contrabass).

A wider variety than you might think!

We don’t only service “Symphonic Strings”, the main string instruments of a “Western” orchestra. The Strings Service Centre also repairs, modifies and maintains ancient instruments from Asian, Middle-eastern, African, Latin American, Slavic and Nordic traditions, just to name a few. These include harps, lutes, mandolins, ouds, erhus (Chinese violins), sitars and bouzoukis, just to name a few. We also service the bodies and electronic components of electric violins & violas, electric cellos and electric double basses.

Tools we use

A strings workshop isn’t complete without all its unique tools. You’ll find everything from chisels, to clamps, saws, hammers, mallets, sandpaper, sharpening stones, onehand planes, sharpeners, soldering irons, soundpost setters, a variety of varnishes, resins, oils and dyes and much more. Another reasons to sometimes let the pros handle the job.

General care tips from the department

This topic is often neglected, which is why we give you a few care tips from the department. String instruments generally have an oil, spirit or nitro finish. Oil, spirit and nitro are the respective solvents of the various paints. In principle, no harsh cleaning agents such as denatured alcohol, nail polish remover, etc. should be used to care for the paintwork. Water is also unsuitable for cleaning the paint.

Common care products such as Bellacura, Viol, Petz Cleaning Fluid, W.E. Hill & Sons Cleaning Fluid or Luthier Cleaning Fluid should be used to remove rosin, dirt and polishing. The care products are to be applied with a soft microfiber cloth and after a short time polished with a soft cotton cloth.

Adjusting the bridge

We receive a lot of inquiries about the adjustment of the bridge (which has to be done in-house for transport reasons) for instruments from our own brand Roth & Junius.

Here we want to go into more detail and explain how to adjust the bridge step by step:

  • Place the bar between the F-holes in the middle of the inner F-hole notches.
  • Now place the bridge on the top with the back straight towards the tailpiece.
  • Place the strings on the bridge in the notches.
  • Please note that the feet of the footbridge should always stand with their full surface on the ceiling.
  • After tuning, the bridge may lean towards the fingerboard, in which case you should get it back into position as soon as possible.
  • The experts from the string department will show you how this works in our “How-tovideo below:
