The Academy Super is an EMO stencil and is virtually identical to the Rudymuck 4M but this instrument ,like the EMO it was copied from ,does not have the A change control rod. As with all of these balanced action trumpets it owes a lot of its design features to the Selmer balanced action models with comparable blowing characteristics.Of the 4M,s I have this my current favourite along with my CONN 28a trumpet
Also listed under Rudymuck instruments.
