Let me know what you think
Hardly. Your arms aren't much higher than a trumpet player's. I've always had an easier time breathing while playing one of these than I've had while using a sousaphone. I even feel that, for marching, it's easier to breathe on these things than either a sousaphone (which puts one arm at your side) or a concert tuba with a harness (not any better than carrying a big bass drum).reitan wrote: Isn't it like making a snowman in hell to breathe properly while playing this thing? With your arms upwards and a heavy weight on your shoulder, I mean?
Well, that's the bonus...btw: If someone came marching towards me with that particular tuba - I'd be running the other way
It's not that big, weighing about 19 lbs. (maybe 20-22 with the additional valve?) with about a 17-18" bell and a "bottom" bow about the same size as a Mirafone's.imperialbari wrote:It looks like it is nickel plated, which would make me guess that the body comes from DEG-Dynasty.
Not sure any more, but the specs Leland added, sound lighter than convertible horns.reitan wrote:We don't have a tradition for these kind marching-tubas in Norway, so I have never played one. I have seen several pictures of these instruments, and it strikes me: Isn't it like making a snowman in hell to breathe properly while playing this ting?

I'm certain those contra balance well. When I marched that con, it wasn't bad. I marched trombone the year before, and it seamed less balanced than the tuba. The Conn was a 4/4 size horn I'm sure. It was bigger than my Olds, which is a big 3/4 horn. I ended up with the valve cluster over my sholder, and once it was up (not that easy form a H.S. kid) it stayed fine. Now the metal sousaphones in college were another story. Toses beasts are heavy, and kill the sholuder.Leland wrote:Yeah, this horn isn't terribly heavy. Plus, they're balanced better than most convertibles that have been made. Yamaha's 3/4 sized convertible, while light, is a bear to carry because it's so short, and therefore most of its weight is out front, being supported by the arms. Larger, longer contras, especially with leadpipes that wrap around the wrist (like on the Marine D&B contra I posted in the "Valves valves valves" thread), actually balance better and are easier to manage while on the shoulder despite weighing quite a bit more.
Are you sure? Every time I see a "15j" the pics are top action valves, not front. Like this oneJeffrey Hicks wrote:Conn 15j. Same as the current 12j with a conversion kit. nice sounding but still not as a good as a good sousaphone.
That sucks. To use the same name on 2 horns that different. Any idea when the switch happened? The horn the school had was new in 1987. How can I find the one I wnat, instead of that one? I asked Conn and got no response.Jeffrey Hicks wrote:Yeah. I am pretty sure they were given the same name. That particular 15j is the copy of the King 1140 which is a pretty lousy horn in its own right.
So the 12j is convertible? Or available as an option? The Conn pages didn't show a convertible front action horn. For than matter no one sems too. I was starting to think I halucinated the horn.The original 15j is just like a 12j with an adjustable lead pipe and switchable first and third valve slide.
