Used Bach Mercedes 879L BBb tuba. 4 front action pistons, lacquer finish, includes gig bag. Nice condition older tuba, with a few minor dings, dents, and scratches. Everything works like it should, and it plays very well! There is evidence of red-rot around the valve cluster, but not a major problem at this point in time.

Bore: 0.689"
