The Blessing BM-400 Series Marching F is an excellent addition to any marching band. This horn has wonderful response and its 11 bell creates fantastic projection. This instrument has a .460 bore, 1st valve thumb saddle, and adjustable 3rd valve finger ring. A wonderful horn to blend with the powerful music of the band, the Blessing BM-400 Series Marching F comes with a case and mouthpiece.
