Why don't we see many used 321 f's and has anyone toyed with extending the f to make an eflat version? I have played an 822 lengthened to eflat and it was killer.

I'm constantly toying with extending a YFB-621 or (more realistically) cutting a YCB-621 to Eb (or taking the same body student tuba (103) and putting another .689 valve section on it in Eb).

The only reason I haven't has been money... and the certain confusion in my head should I attempt to play two instruments with an identical grip and different fingerings... the grip tells my brain what key tuba I'm holding ;-)

The 621 Fs can do any "F" job. It may never be perfect, but it's very flexible.

My gripe with the 822 F has always been that it was an Eb tuba with too little tubing and without the benefit of a compensating valve section. Never struck me as an F tuba... Great instrument, but not the "F" timbre I expect.

The YEB-381 is quite nice -- 5th valve is a dependent rotary, contained within the 4th valve tubing. Mine has the 5th tubing lengthened to a flat whole step by Lee Stofer, and has a valve lever extension so I can use the right hand thumb for it. A great quintet horn.
