The KTR411 and KTR412 marching trumpets were made to the specifications of the DCI Champion Blue Devils. With a revised valve cluster location, the ergonomics of these trumbets are balanced for the needs of the modern pageantry arts ensemble. With a 5” bell and available in a .459" bore (KTR411) or .464" bore (KTR412), these trumpets are powerful instruments ready for the demands of the marching field.
