The big brother to the Rudoulf Doetsch, the Wilhelm Klier is a step above for the advancing high-school level student. The Klier instruments are made with higher quality German tonewoods, which have been aged for over fifty years. The hand applied varnish is similar in look to the Doetsch. The tone is smooth, clear and precise. This instrument is perfect for the advancing student who takes practicing seriously. Our vintage instruments are previously owned and immaculately maintained.
