A good instrument is one that you enjoy to play. Each musician is unique, therefore your taste in instruments is as well. Tim Duerinck has experience working with musicians that have very different requirements for their instruments. The playability and sound of an instrument are influenced by the materials used, the design and the set-up of the instrument. As such a wide variety of sounds can be created by changing these parameters! The best way to find out what you prefer is to meet, try some instruments and discuss your personal taste.
In some cases, meeting in person is not possible or advisable due to travel restrictions or travel cost. Do not hesitate to make contact and discuss alternatives.
