I have my own ideas about how these tubas play and sound; I will keep them to myself unless they end up being worth contributing to this thread. I want to read some discussion by others about these horns as a collection of components in this thread.
So, firstly: the needed tuning bit. A nice idea, but the bits suck, and IMHO the leadpipe needs to be a single piece, in this case. It is VERY SHORT, so it tapers up to .770" way too fast, as I see it. This could contribute to their hoot-o-phone rep for soft dynamics. Probably not, but it could.
Next, the bell collar: I have played about 25 examples of the 2165 family of horns. Many of them had the tone ring. Many did not. I felt the tone ring did not work at all on a lot of the horns, making them "indelicate war hammers" instead of musical instruments. In a few cases I liked the ring a lot, so who knows what it is that I am associating with the rings. Anyway, the rings were an attempt (according to Gerhard Meinl when I spoke with him in the early 1990s) to see if a detachable bell horn has any acoustical advantages over a one-piece bell due to that added weight right in that area of the bell. He did not mention the Conns, but the King 2341 came up as an example. (Apparently, "someone" involved in the design process was convinced that this was a needed thing, so it was added.) Whatever. Soldering one into the bell is something that can be reversed if it turns out to be a mistake. But a detachable bell will *always* have that knot of weight right there. So, is that a good or bad or neutral thing?
Also, the sheer, silly size of the bell flare. I detest large bells and how they sound. I just can't stand them. There seems to be a sweet spot, and these horns seem to be from the era when they still did not have this dialed in, fully. I will admit that I dislike old, Bohemian/Germanic "flareless" bells just as much. The big bells are like lobbing peanut butter balloons while the super-small bells are like tossing darts at the audience. The archetype for a BAT bell seems to hover between 19 and 21 inches, with 20 seeming to be very common, and 19 being a close second.
The large, two-piece bell on the Conn 2xJ series of horns, IN MY OPINION, is the source of many of the things I dislike about them. I have only seen one horn where any real money and time were spent to really trick out one of these, to include a very nice bell. I hear a lot of salesmanship jabber about how great a horn it is, but it ends up on the block for sale far too often for this to be completely true. I also hear rumors that once you clear up stuff with a better bell that the intonations issues become much more clear and defined, in a bad way. Things that were always out but that were very easy to lip suddenly became very tightly slotted, and occasionally irreconcilable. Is this true? Does anyone really know?
So, I hate the bell, I absolutely blame the too-short leadpipe for some stuff, and I do not really like the valves or their orientation, and I do not play BBb tubas anymore. So why am I kicking over this log? I want to know if anyone has experience with the bugle in projects, meaning the bottom bow through the main slide. I like these because they are like a BAT, but smaller. It seems that this set of parts *should* make a mini-BAT (akin to the Gronitz PCK or the Kalison Pro 2000), that, with the correct bell could be an excellent CC tuba. The issues that Holton 345s have when cut seem to stem from the horn having too much fluid volume for the length of the open horn. These Conn bugles seem to me to be an alternative to this, with a bugle volume more appropriate for a 16' pipe. So why do they not seem to work out? Is the taper just too funky?
Could it be that the parts were designed poorly? (From C.G.Conn? BLASPHEMY!)

I have two of these, and both are good players. Not great, mind you, but they have decent intonation (after a lot of resoldering of joints and cleanup internally) and they have that foghorn sound I just love, but the response is good, charity is good with the right mouthpiece, and overall they do not suck. The bells are really tall, and there is a lot of slow-taper or cylindrical tubing in the main horn that trimming to the branches would not have to be excessive, and re-tapering the ends would not be difficult. But I do not want to chop one up unless I have a bell that I *know* will work with this sort of taper and that offers excellent clarity and color. The Kniffen horn has a Miraphone Siegfried bell. Has anyone played this tuba? Has anyone seen any other 2xJ horns with different bells that seemed to make the sound less band-section-like and more orchestra-solo-voice-like and that did not ruin the intonation or slot it so tightly as to make it hard to play well in tune?
I plan to restore the better of these two horns as an unlacquered 24J and sell it to fund a bell for the other one. (Alright, TBH I will cut up the better of the two as the lesser seems to be about as good as most of the fans of these horns seems to want to spend money on.) Again, I am looking at two years out, and need to find a bell, or I need to be waved off in no uncertain terms because it will end up being crap. (No, I will NOT restore it as a 24J. Period. It will be made into something, But maybe not a CC tuba with front valves. So don't wave the "history" flag at me. That is bunk with these tubas, which are dead common in many places and not worth much money unless in stupendous condition. Thanks.)
This is a thread to discuss the reasons why these horns never turn out to be good project instruments. Is it because they just stink, or is it because no one has yet found a good use for them where stuff works well? I am mostly interested in intonation and tone issues. I like how they play but dislike the sound. I have not had intonation issues with them like others, but I admit that I have not played many of them with others, so I don't know how easily they are lipped to fit into well-tuned chords in different inversions. I really like the inner and outer branches, though, and they seem like they would be more popular to screw around with. That they are not is why I am asking these questions.
Thanks. I will enjoy reading anything any of you decide to share, especially photos.
