Bach · Professional · 36B · 1930s–present
Bach started making trombones in the Bronx in 1928, and the model 36 arrived in 1932. Bach's 1935 catalog sold it for first trombone in large orchestras and wrote that no player could reach the limit of its fortissimo. The B suffix adds a rotary F valve, which lets you play the chromatic scale down to the pedal notes, and the 36B was already in that 1935 catalog. The bore is 0.525 inch, a medium-large size between the small jazz horns and the 0.547-inch 42B that Bach designed for symphony and opera sections. Today's 36B has an 8-inch one-piece hand-hammered yellow brass bell, chrome-plated nickel silver inner slides and a traditional-wrap F attachment with a standard rotor. Bach now pitches it for symphonic and solo playing. It's built in Elkhart, where Bach production moved in the mid-1960s. For a used buyer the size is the appeal. It's a smaller horn than a 42B but still has the F attachment for low notes. Check the hand slide first and the rotor second, since both are fitted to fine tolerances.
A step-up or college horn for a trombonist who needs an F attachment, not a first trombone. If your player's teacher asks for a large-bore horn, look at a 42B instead.
Build and case36B
Bach trombones have their own serial list. Conn-Selmer's chart puts them at about 8,000 in 1965, 11,000 in 1970, 25,000 in 1977, 45,000 in 1981, 65,000 in 1985, 91,000 in 1990 and 115,000 in 1994. A serial starting with a letter marks a student or intermediate Bach, not a Strad.
The hand slide is the expensive part, since its tubes must stay straight and parallel to work. Rotors need regular oil, and a dented slide or sticky rotor is technician work.
More on this in our trombone buying guide.
Buying guide
We'd buy a US 36B with its case, like the silver one with two mouthpieces at $1,750 delivered, the bottom of the $1,750–3,850 band. There are at least 18 for sale, many from Japan dealers, and new ones from US dealers ask $4,499–5,158, so that pick saves about $2,750 on new. The hand slide is the expensive part, so ask for a video of it gliding the full length and of the F rotor turning, and budget for a shop check-up. This is a step-up or college horn for a player who needs the F attachment, not a first trombone. Skip the two Japan listings that share a photo with other dealers and the one titled trumpet whose photo is a 36B with award badges pasted on.
