Pre-owned Conn Wonder Cornet in Raw Brass w/case
 
The C.G. Conn Wonder cornet, introduced in the late 19th century, was highly regarded for its innovative design and superior sound quality. Patented by C.G. Conn in 1886, this instrument was praised for its "noiseless valve action" and the ease with which it could be played across its entire register, from lower pedal C to C above the staff​.
