I'm helping some friends out by testing this new toy. It's a rotary valve that fits onto the 4th valve slide of a Yamaha 321 euphonium, making it a 5-valve model. It's like having a German-style valve setup on a piston euphonium. The rotor can be set to flat 1/2 step, for a 4+5 low E, or flat whole step for a 4+5 low Eb. Low C and B are no problem to play in tune. You just get your left thumb in there, and it's easy to reach. And you can take it off when it's not needed.
Yamaha actually made this part at one time, but it's been long since discontinued. So what's the TubeNet opinion? Is this a good frugal alternative to the pricey compensating euphonium for those who like to play low? What should the tuning be? Flat whole step? Flat half step? Both? And what do you think it's worth? (Inquiring minds want to know.)
On another note, the old Yamaha 321 euphs had a long 3rd valve inner slide. You could pull it out to tune the 3rd valve to 2 whole steps (like 2+3). I believe these long slides tended to get stuck easily, so sadly, they now put a short slide in there. But today I noticed that even though the inner tubes are short, Yamaha didn't fill up the inside of the long outer tubes, so there's a gap in there. A long slide could be made and it would still go all the way in. Would this be worth doing? The idea is that if you tune the 3rd valve to equal 2+3, it's Belgian style tuning, and you can then play a low C in-tune with only 4 valves. Then you can play Strauss all you want - just pull the slide out a bit before the low riff, in the same way that a single valve bass trombone player might pull the F-attachment to E before a menacing riff. Opinions?
This horn will be on display at Trombone Day LA at Cal State Fullerton this Saturday February 6, 2010. http://www.tromboneday.com
