Products marked as 'ex-demo' are offered at a reduced price because they have been used for inspection, demonstration or marketing purposes by the manufacturer or seller. They are not factory-sealed, but are sold 'as new' and are subject to a full mechanical warranty. In some cases they may have a limited cosmetic warranty. Item-specific condition reports are always available.
The Conn 10DE ‘Symphony’ is an enhanced version of the Conn 10D professional F/B-flat model.
Modifications include two sprung water keys, improved valve caps, an adjustable finger hook, and a redesigned F branch to open up the sound and give a little less resistance.
