IMO, the piston and rotary really are two different horns. Not just the valves but they play different. The sounds out front, to me, are similar, but they go about it in different ways.bloke wrote:I've played the rotary version and, although I noticed that it offered very good intonation - particularly for bit-larger-than-4/4 tuba, frankly I was a bit nonplused. Neither the sound nor the response rocked my world.
IS the piston version of the B&S PT-6 CC tuba MUCH BETTER than the rotary version?
The rotary has that rotary valve smoothness to response and dexterity while the piston seems to maybe slot more and sit on the note firmer once established. This is from limited exposure to behind the mouthpiece of them.
When I have played PT-6s I have had your same reaction. "What is the big deal?" They gave me feedback sorta like what I feel like when I try to play a Rudy Meinl. They feel a little awkward and foreign to me. I just feel unsure of what is coming out the bell. Perhaps it is my background on Hirsbrunners and the like.
My "heritage" on tubas is as follows:
Jr high
Conn BAT 3-valve BBb
High school
Miraphone BBb 4u rotary
Miraphone CC 185 5u rotary (5th valve never worked)
Undergrad
B&S PT-4 rotary (older style)
Kalison Daryl Smith CC piston
Hirsbrunner HB-21 CC piston
Grad school
Hirsbrunner HB-21 CC piston
Audition
Hirsbrunner HB-21 CC piston
Job primary horns
Miraphone 4-valve Sousaphone BBb
personal horns
Yorkbrunner CC piston
All of the above are gone now
Currently used horns
Conn 3-valve Sousaphone BBb
Hirsbrunner HB-2p CC piston
Meinl Weston 2000 CC piston
Miraphone 186 5u BBb rotary (only used to memorize marches)
Now with my instrument resume out there, perhaps you can see my bias. The PT-6's feel more like my PT-15 F tuba than any of the other tubas I have used.
Ok, enough with the "How it feels"
The PT-6 is all about the out front experience, at least I hear it that way. The horns are never a handicap and has the efficiency in sound to really carry well. Why? No clue. Ask Mr. P that one. I just know that when I am listening to people out front, my ears gravitate to the sound of the PT-6.
This would be a good horn to test with either someone out front or a tape recording running in an ABC comparison.
