The Bach 36 Convertible Tenor Trombone, serial 210xxx, represents one of the most versatile medium-bore designs in Bach’s lineup.
This particular example was custom-built by the respected brass technician Todd Clontz of Russo Music in Baltimore, MD, and remains a fine example of a carefully prepared professional instrument.
It features the standard Bach 36 bell with a removable neckpipe, enabling the instrument to function as either a straight tenor or to accept an F-attachment when desired.
The standard-weight 36 slide includes a custom threaded leadpipe collar that accepts either Shires- or Edwards-threaded leadpipes for additional tonal flexibility.
The original Bach leadpipe was included at the time of sale.
The horn’s slide action was superb, with excellent alignment and response, and it showed minimal playing wear, presenting almost like a new instrument.
As a medium-bore (.525) trombone, the Bach 36 Convertible is especially valued as a crossover horn, equally suited to jazz or commercial work, pit orchestra, pops concerts, or as a primary instrument for advancing students.
At the time of sale, the trombone was pictured with a Marco Magi tenor case, a lightweight yet protective design that also accommodates a large-bore tenor with F-attachment.
The case was offered as an add-on at a discounted package price.
This page remains in our archive to serve as a trusted historical reference for anyone researching the Bach 36 Convertible model and custom-built examples by leading brass technicians.
