There have been other flamethrower trombones, but none can match the Frankenhorn in terms of sheer musical firepower.
This is a working playing flamethrower trombone that has fire on demand. It is made up from plumbing, torch, and compressed air parts. It took about two weeks and a couple of weekends to complete. It has a 21 foot range with the fireball, and a concussion wave of 150 feet. It can be difficult to play since it has a recoil.
