This is a group of leadpipes by S.E. Shires for bass trombones that have a .562" upper hand slide tube bore. (That means nearly all bass trombones.) Made in Hopedale, MA, these are threaded at the top to fit into a receiver on S.E. Shires bass trombones. These pipes may also fit several other brands, including some Kanstul trombones. Your favorite brass technician can make it work. (Maybe he will have a large enough hammer.)
These pipes are made in 5 sizes and have options for length and materials. When you purchase an S.E. Shires bass trombone, three leadpipes are included, usually sizes 1, 2, 3 in yellow brass. We can substitute other sizes at time of purchase depending upon availability.
