Overview
The Bach 36B remains one of the most versatile F-attachment trombones ever produced. Combining a .525" bore with an 8" bell and traditional rotary valve, the model occupies a unique position within the Bach lineup, offering greater breadth and depth than a small-bore trombone while maintaining more agility and efficiency than a full-size symphonic instrument.
This example, serial number 136423, dates from the early 1990s and underwent extensive professional servicing during its time at The Brass Exchange. The rotor was fully serviced, the valve casing cleaned and polished internally, and the instrument carefully prepared to maximize its playing potential.
A unique feature of this particular trombone was its raw brass appearance. The original lacquer had been professionally removed from both the bell and handslide, leaving a polished raw brass finish that gave the instrument a distinctive visual character while highlighting the craftsmanship of the underlying brasswork.
Recognizing the quality and potential of the instrument, the handslide was also sent to a specialist technician for final professional setup and optimization prior to sale. The result was a well-prepared Bach 36B that delivered the versatility and reliability for which the model has remained popular among advancing students, educators, commercial players, and serious amateur musicians.
