It's a 20J.

The Conn 20J Upright Recording Bass is the full name of the tubas used by the Jacksonville State University Marching Southerners. Although used on the field, the 55 lb horns are actually concert instruments. This gives the Marching Southerners its famous, deep-bass sound.

"Who is crazy enough to strap on a 55 lb instrument, and march all over a football field for 10 minutes at a time," you say?

We are.'s not just an instrument...IT'S A STATE OF MIND.


What in the world is that thing?
