Used, custom made by Martin Wilkes: EEb helicon in really nice condition. It was originally a 3 valve instrument and the 4th was added at some point prior to the current owner acquiring it. It has also had a valve re-build at some point previously. There was a bit of custom work done to this horn: detachable Keefer bell and a detachable valve section. This is a custom "one-of-a-kind" helicon. Brushed lacquer finish, includes gig bag and a mouthpiece.
