The Lineage of the King Marching Mellophone
King’s marching mellophone has been one of the most popular mellophones since its introduction. While the Yamaha YMP-204M is the current standard of the mellophone world, the King 1120 and 1121 still see a lot of use in marching bands, most notably HBCUs. But the story of this design did not begin with the King 1120 - it actually has direct ancestry back to the bad old days of the drum corps G bugle.
L-R: King K-50, Kanstul KMB-180 (early pattern), Kanstul KMM-280 (early pattern), King 1120, King 1121 Ultimate
All five of these instruments share the same basic design, and all (except possibly the 1121) were the brainchild of the same person: Zig Kanstul.
These instruments are pictured in chronological order from left to right: King K-50, Kanstul KMB-180, Kanstul KMM-280, King 1120, King 1121 Ultimate.
This design began with the King K-50 mellophone bugle in G, a legendary mellophone that was the best of the 2-valve mellophones. Zig Kanstul designed the full line of King K-series 2-valve G bugles, and while all were good, the K-50 mellophone is one of the most revered models of the line. And it’s easy to see why - the K-50 is the sports car of the mellophone world. It plays easily, sounds great, and screams better than anything.
When Drum Corps International legalized three valves in 1990, Zig Kanstul came back to the K-50’s basic design and updated it with a 3rd valve, but this time under his own brand. The early Kanstul KMB-180 mellophone bugle in G was the next step in this design’s evolution. You’ll notice that the KMB-180 deviated slightly from the K-50 design by having the leadpipe enter the 1st valve from the other side, rather than angling to get around the 1st valve slide and entering the valve from that side. The leadpipe is also shorter than the K-50’s, with that length moved to the taper after the valves. This instrument also introduced the unique 3rd-valve slide wrap that remained a distinguishing feature of the design until the King 1121. I’ve never played a KMB-180, but I did own an early-pattern KAB-175 alto bugle, which is the same instrument as the KMB-180 with a smaller bell flare. That instrument was an incredible player that felt effortless in the hands, much like a K-50.

It didn’t take long for the Kanstul brand to branch out from G bugles, and the KMM-280 marching mellophone in F was this design’s next iteration. It was the same instrument as the KMB-180, just with a longer leadpipe and valve slides to bring it down a whole step to F. This was the real blueprint for the King 1120, and I would love to get my hands on one to compare the two. After this, Kanstul redesigned their mellophones and altos (in both G and F) into a completely new design, so the Kanstul Musical Instruments branch of this design’s lineage ends here.
Next up was the King 1120, which came about when King hired Zig to help design at least some of their marching brass. (The 1122 Bb marching horn is likely another, as it looks to be the same design as the King K-60 French horn bugle. I also wouldn’t be surprised if the 1124 marching baritone is also Zig’s work, being as it has the same wrap as the Kanstul 290 marching baritone.) Visually, the 1120 looks the same as the Kanstul KMM-280, apart from the leadpipe. The 1120’s leadpipe returned to the K-50’s design, with the longer wrap and routing around the 1st valve slide. The 1120 became one of the most successful marching mellophones ever, used by many high schools and colleges for many years. I used my 1120 as my gigging mellophone until I got my Yamaha 204, and the King never let me down. Because so many were made and used, they can easily be found for very cheap (around $100) on eBay. In my experience, out of all of the dirt-cheap ex-school marching mellophones out there, the 1120 is by far the best option. The 1120 has also been stenciled as the Conn 132E and Bach B1105.
Eventually, King updated the long-running 1120 and created the 1121 Ultimate. This is mostly the same instrument but with an angled leadpipe, re-wrapped 3rd valve slide, and 3rd-slide finger ring. Early 1121s also had a spring-loaded 1st valve slide, but the current ones do not. I’m unaware if Zig was involved in the 1121’s design, but it was only a minor update anyway. The 1121 was recently succeeded by a few different mellophone models that have made everything much more confusing. Based on what I can tell from product pages, these are the models and their differences from the 1121:
K20: no angled leadpipe or 3rd-slide finger ring, nickel-silver pistons (instead of Monel), half-inch smaller bell (10” vs. 10.5”), sometimes (but not always) with a brace on the bottom bow, already discontinued
KMP411: no angled leadpipe or 3rd-slide finger ring, half-inch smaller bell (10” vs. 10.5”), more open 3rd-valve slide wrap, notched main tuning slide, adjusted valve cluster location, sometimes (but not always) 1 or 2 braces on the bottom bow, apparently designed by the Blue Devils
KMP611 Ultimate: no angled leadpipe, half-inch smaller bell (10” vs. 10.5”), .466” bore instead of .468”, nickel silver leadpipe, and a redesigned bell
KMH611 Ultimate: a KMP611 with a French horn receiver and angled leadpipe, which appears to be the end result of the King/Patterson hornette project
The three KMP models are already out in the world, but there are still K20s and 1121s in stock at some retailers so the transition isn’t entirely complete. I’m curious to try the new models to see if more incremental changes from the basic 1120 design are enough to make them truly compete with the Yamaha 204. While I did manage to snag my 1121 for very cheap, I have a feeling it will be a long time before cheap K20s and KMPs start showing up online.
As an interesting final note, the Yamaha line of marching mellophones was based on the cornet-wrap design of the Olds A-42 marching mellophone (which was stenciled by quite a few makers including Bach, Blessing, and Reynolds). The Olds marching mellophone was the first F marching mellophone, derived from the G mellophone bugle and designed by…you guessed it…Zig Kanstul!
So, the two mellophones that have dominated the marching arts for years are either an actual Zig design or a derivative of one. In fact, as the Jupiter mellophone is also essentially the same design as the Yamaha, the only current marching mellophone that isn’t a Zig Kanstul derivative in some way is the Adams MM-1, which bears a closer resemblance to the Dynasty mellophones.
