Vincent Bach 36B B-flat/F tenor trombone

The ‘36B’ emerged during the mid-twentieth century as a medium-large bore professional tenor in the Vincent Bach Stradivarius line. Featuring a .525-inch bore, 8-inch one-piece hand-hammered bell, and traditional wrap F-attachment, it was designed to balance projection with agility. Introduced during a period when large-bore orchestral instruments were gaining prominence, the 36B filled the crucial middle ground between small jazz tenors and symphonic .547-inch models. It became a conservatory and freelance staple, shaping expectations for the versatile American medium-large bore trombone.
