The Ring Wagner Tuba is a marvelous instrument but has limitations on the F side as would be expected in a compensator and as has been described by John Ericson on his blog. I’m wondering if anyone out there would be interested in a full double Wagner Tuba that would be more affordable than the European options of which there are many wonderful ones. But quite expensive. The Hoyer Double is listed at over $13,000 for example. Any feedback would be appreciated.
