The renown design and expert workmanship from Zigmant Kanstul is heralded in this new F tuba - the first production F tuba made in the United States. Inspired by the classic J.W. York instruments of the early 20th century, this innovative design addresses all the needs from F tuba players looking for an improved instrument: outstanding intonation, even response throughout the entire range of the instrument, and a dependable low C with a natural full resonance not found on other F tubas. The Kanstul F tuba is a new voice in the modern symphony orchestra...it bridges between the bass trombone and tuba sound to fill a void that has long existed in the low brass section. It has the ability to sound absolutely pagan - so throaty and powerful, almost savage at times! It has a center and definition and core that makes it easy for me as principle (trombone) to find and sit on top of.
