The story of the Conn 6D begins in the early 1920s with the introduction of the original “6-D” model. Equipped with a piston change valve in the “Schmidt” style, this 6-D was Conn’s first double horn. The 6D was revised in 1935 with a rotary change valve to much acclaim, quickly becoming “…the favorite of big symphony players.”
The next-generation 6D takes the critical mouthpipe, first branch, and bell tapers of the historic 6D and pairs them with the chassis of the iconic Conn 8D. The switch to the durable nickel-silver Kruspe-wrap chassis of the 8D brings many of the construction advances to the 6D, including revised manufacturing processes, acoustic enhancements, and ergonomic improvements.
The combination of yellow brass slide crooks, first branch, and bell with a nickel silver mouthpipe and branches blends the warmth of yellow brass with the clarity of nickel silver. New CNC-machined mouthpiece receivers ensure the critical mouthpiece insertion depth is the same from instrument to instrument.
Like its predecessors over 80 years ago, the revised 6D is popular with professional musicians who praise its quick response and compact sound with a wide palette of tone colors. Teachers have also praised the more compact wrap and standard tuning slide arrangement as well as the easy control of the small-throat bell.
