Joe, I have to compliment on your newest facelift. It is much more successful than the one preceding your avatar. Was Code D the designer?
I see some intra-ensemble aspects in this matter, so I will start with far-far ago personal experiences:
I played horn, 2nd at that time , 1st later on) in a local symphony, where the conductor, the leader (Konzertmeister), and I were just about equally well educated conductors. The conductor was very dependent on the leader on getting the strings right.
The leader and I made some agreements on how to make things work in matters, where the conductor had no experience at all.
We did a Koncertpolka for two violins by Lumbye, and the string section worked less than optimally intonationwise. I had done that piece in a quite prominent concert, but on bassbone, so I offered to bring my slide-o-phone for that piece. As soon as the bass-line was laid out perfectly in tune, the strings lined up. And the leader expressed his great satisfaction, because even the soloing became much easier.
My point is, that as much or as little we bass-line people are paid to entertain the ticket-buying public, then most of our work is to uphold intra-ensemble functions, which make the other players work well and sound good.
In that context Joe’s contractor isn’t too smart. With the given seating on the stage, Joe would do a lot for the ensemble with the helicon showering his musical genius out over the whole ensemble. With a front action 6/4 mastodontophone Joe’s genius will be reserved for the ticket payers, and the ensemble will have a hard job in catching up with him.
As for accordion players: I have been married to a such one. And I enforced the rule going for my own instruments: only buy the best one affordable. And my ears were the final judges. I cannot play the accordion, but I can repair and maintain one short of tuning it, which takes special tools.
A duo of tenor bone and accordion is very effective in dance situations. Add a drummer and things get perfect.
