Willson 3200XL 5V F Tuba

From Willson: "This new large-orchestra F tuba is appropriately named the XL and takes the place of the 3200 FA-5 tuba. The new XL is a completely revised design - even its appearance is totally new. Like its predecessor, the XL F tuba has a sensational low register and a tone with plenty of body, which makes it exceptionally flexible.

The main bore is conically shaped, using the manufacturer's own empirical values. This yields absolutely pure pitch and intonation in all registers."
