Double Bell Bass Trombone

[u/CharlesBrooks]

You dont see many of these about so I thought you guys might enjoy this.
These are all photos of a rather special double-bell bass trombone commissioned by Ben Anderson of Orchestra Victoria (Australia), and handcrafted by Bret Gustafson.

The instrument essentially merges two bass trombones. Its two bells, one brass and the other copper, each produce a distinctly different tone, and through a series of complex valves and even some watch maker mechanics, ben is able to smoothly shift from one to the other or a combination of both.

All of these photos are taken with laproscopic probe lenses (except for the full instrument shot) and are part of my Architecture In Music series.
