Let's see how quickly we can get this thread off topic discussing either Ron Paul, alligators, or two-sided tape.
I'm only one of - likely - several million in the "tuba world", so someone might appoint themselves in charge of going around and asking the others.What is the tuba world's opinion?
Compensating euphoniums, in the original goal, was to fix some intonation issues. The reality is that doing that also created other intonation issues. If you were to spend some time on Dave Werden's site and his intonation graphs here:LeMark wrote: ↑Sun Jul 28, 2024 9:21 am I don't see how a compensating valve system would effect an instrument unless you are using the compensating valve, otherwise is has zero effect. If the euphonium is out of tune above a low C, then it has to do with the taper of the bugle, and has nothing to do with the valve section. As far as low C and below, are you saying a compensating valve section is more out of tune than a non compensating? I think it would be pretty easy to counter that argument
As far as bloke's idea, I've been a fan of the idea of a 3v compensating Sousa for a long time. As a teacher in Texas, I have band directors coming up to me all the time asking what we can do about the out of tune FFF low B natural whole note the idiot composer wrote into the finale of their precious marching band show
Reynolds had such a mechanism on their tubas in @ 1959 for a couple of years, both push for 2nd space C and pull for 1+3 and other combinations, that returned either way for 1st valve notes.arpthark wrote: ↑Mon Jul 29, 2024 6:57 am Was recently chatting with someone who took an Eastman front-action compensating Eb valveset from a model 853 and pasted it onto a King full-circle Eb sousaphone.
If I wanted a fully chromatic and in-tune Eb sousaphone, I would probably look into something like that, but have it be in a 3+1 setup, somehow.
Having not much to offer besides the above, two-sided tape, and Ron Paul, I think a 3v compensating BBb sousaphone is an awesome idea. My 36K (pictured in my avatar pic) has a top-adjustable first slide, but I'd love for that be a spring-loaded "push in for C in the staff" slide that returns to its original position rather than a hand-operated "push in for C in the staff and pull out for low C and B nat" slide.
Yes, because the first thing I think of when I play a magic Besson Sovereign euphonium with the most colorful euphonium sound ever is "aww, what a shame, the compensating system took out so many harmonics."Richard III wrote: ↑Sun Jul 28, 2024 8:50 am For my ears, compensating systems are one of the worst things to ever happen to brass. But I'm coming from a euphonium concept in my world. The more weight, the more bracing and the more complex you make a brass instrument, the more harmonics you lose in the sound. Supposedly the trade off is better intonation. I just don't get it.
Sure, except for compared to literally anything else.Compensating euphoniums have some of the worst intonation in the world.
Everything is a trade-off. There is no perfect system (especially with only 3 or 4 valves), and anyway the tapers are what affect intonation...not how you route (or don't route) your valves. Trombones with no valves still have intonation quirks.Richard III wrote: ↑Sun Jul 28, 2024 5:21 pmCompensating euphoniums, in the original goal, was to fix some intonation issues.

This is a red herring. The only way this kind of data set would be real evidence of intonation differences between compensating and non-compensating is if you took the exact same make/model, made by robots (and not handmade, to eliminate variation), and built it in different valve configurations. The only telling factor about the Adams Sonic vis-à-vis its valve setup would be as compared to a 4-valve compensating Adams Sonic with the same specs.Compare the Adams Sonic, a non comp ephonium with any of the other euphoniums, you'll notice the difference.
The valve section on the JP is way better built than King as it is a copy, but the intonation of a JP compared to an older King is not quite as good - though it is good. Of course, they cost less than half as much and are sturdier than King as well. I just don't think he wants to step out and be the first person who offers a whatever. That's just not his style.
