Could the triggers for the two rotors on a 6 valve tuba be arranged like a bass bone's (this style, http://www.oberloh.com/gallery/edwards.htm" target="_blank, where both are controlled by the thumb) instead of the 4+2 or 5+1? This would allow you (if possible) to still have a free hand for slides, water, or a phone/ipod if the piece is boring

Most bass trombone players hate the split thumb trigger arrangement. Virtually all modern bass trombones with both the independant and dependant valve designs now use a thumb/finger trigger setup. Many of the older horns have been converted to this kind of linkage.
The trigger in the above link was converted for a very specific purpose due to a disability.

For those of us with arthritic thumbs, any thumb valve is pretty much useless (and eliminates the instrument from consideration for purchase) -- might be one of the reasons that 3+3 and 4+2 were the standard configurations for so many years.

Hi!
I would think independent side by side triggers would be useable, but a nightmare to locate on a Tuba! I think the linkages would be a serious pain to synchronize, especially if their rotors couldn't be placed side by side on the horn. A thumb actuated solenoid might work, set up A, B, or A+B, but where would one plug the Tuba in?
