The Calin Wultur Workshop is a group of string instrument makers in Reghin, Romania, led by Calin Wultur.

It produces instruments that are unique in the world for their workmanship and tone relative to their price. As time has progressed along with economic progress, traditional European centers of luthierie such as France and Germany, that once produced instruments on a commercial level that were of high quality, have grown largely uncompetitive with other regions such as Eastern Europe.

Reghin’s tradition of luthierie does reach back for some time, but, with the exception of a number of talented, individual makers, mainly as a center for factory instruments. The Wultur workshop cannot objectively be categorized as a factory – the work done is largely by hand, and the number of workers is less than thirty. European wood, workmanship, and tradition coupled with economically advantageous locale make Calin Wultur a unique value in string instruments.
