This very fine trumpet has an offset middle valve and a third slide trigger. The bell has a darker color as the alloy has more copper in it, The tone has a lot of core and it is a majestic instrument. It is not as easy to play as my Bach Strad 37 or my Olds Super, but it is a very fine horn and among the best of the trumpets I have owned, and I have owned many trumpets in my lifetime.
