Expert care for yourstringed instrument

Sound improvement and bow maintenance — every service performed with the same dedication as the making of a new instrument.

Service A

Sound ImprovementUnlock Your Instrument's True Voice

A well-made instrument often has untapped potential. Through careful analysis of the bridge geometry, soundpost position, string choice and the balance of forces within the instrument, Pieter can reveal a fuller, more resonant sound.

This is a collaborative process: Pieter listens closely to the musician's description of what is missing — more depth, more clarity, more projection — and works systematically toward that goal. The musician's feedback is central to the process.

What is addressed:

  • Bridge fitting and geometry — height, curvature, foot adjustment
  • Soundpost positioning — location, tension and fit quality
  • String selection — tailored to the instrument and playing style
  • Force balance analysis — bow contact point and string afterlength
  • Nut adjustment — string height and groove profile
  • Fingerboard check — scoop and surface condition

"The goal is not to change the instrument, but to unlock what it already contains."
