Here is a MINT Bach Stradivarius 42AF professional trombone. WOW! The Bach 42 has been an orchestral standard for decades. Many manufacturers have tried but none have matched the dark soulful sound of the Bach 42B which is ideally suited to symphonic trombone playing. This particular instrument features the improved Infinity axial flow valve for an open freeblowing experience, the open wrap F-attachment configuration for a freer blowing trigger range, as well as the Infinity valve's patented construction that will never leak. This instrument has had very little playing time and is in perfect condition. Pics tell the rest of the story! Please feel free to email with additional questions!
