I am not able to verify you on that one, as I never have seen the original version of the 981. I am not even sure, that a sample may be found in my country, as Denmark and especially Norway are "982-areas".
The story about my 981 acqusition is a bit special:
In late 1998 my mortgage company sent me a very favourable lending offer, because I due to my stable payments had reached some sort of VIP-status. I owned just about anything needed from piccolo trumpet through bassbone and euph in high end pro versions. But my only "tuba" was the Conn 26K sousaphone. Brilliant as my morning warm-up instrument, fine for my playing lead in my self-arranged duets with my late friend Ove, and a sure hit in our for-kids concerts.
But I wanted a for real tuba. I was, in early 1999, sent an offer on a 981 from a Copenhagen shop, which had cheated on me a couple of times (I have got my revenges coming out clearly on top of them).
I didn’t want to buy from them, but I tried out anything available in the shop, where I am the company historian (they were founded well over 200 years ago). The Yamaha options were not relevant, as they rattled. Very odd, as my YEP-641 is the dynamically most stable instrument I ever tested aside with my 981.
The 983 came close, but was too smallish.
I went to the cheater shop and tried their 981. The company clerk had pulled the slides, "so that the tuning would be optimal". What an idiot!
I pushed in the slides. Did my flexibility tests, checked the intonation of the sore spots, checked the response by playing fast triple tonguing on every single note in a 4 octave range, tested if I could play my tuning reference hymn in some difficult keys, among them A major.
And then I went back to my "home" shop and ordered them to have Besson make me a 981. Besson didn’t build tubas for storage, but only to firm orders.
My sample arrived 3 months later. It was better than the test specimen I think. Or I had become a better player by practising (with a Danish saying) like death and devil on the lesser models made available to me temporarely.
When I tested my 981 just after its arrival, one of the repairmen said, that he never had heard so fast runs on a tuba. As a recorder player I am used to play with extreme speeds, and a few licks are possible to transfer to the tuba.
The same guy spoiled my range stunt. When I had hit the 16th partial in a chromatic progression to test response, that bad boy exclaimed: "Now he will call out for a horn mouthpiece!"
I am a horn player also and a joke cracker myself, so I bent over with laughter, so no more playing for the next hour.
About the revised shape of the 981 leadpipe shape I have to express mixed feelings:
For a person of my size, 179 cm, with a long torso and a long neck, the reshaping is ideal from an ergonomical point of view.
As I understand the Besson reshaping philosophy, they shape the 982 leadpipe over a mandrel, which is conical up to 0.689" all the way from the receiver end through the point of joining the valve block.
But then the 981 has its leadpipe shaped over a mandrel, which is only conical at the receiver end. The 981 leadpipe only is conical at a length equalling the length of the old Fletch style straight leadpipe. That is: it hits the .689" mark about 60% down its length.
The price paid is, that the lengthened leadpipe causes a shorthening of the main tuning slide. That implies, that part of the cylindrical bore is being moved from a wide bore area, actually the tuning slide is dual bore, to a less wide bore area of the main bugle.
I recognise that fact changing the character of the overall bore profile, but it hasn’t bothered me. In hindsight it may be the reason, why I use a hysterically large mouthpiece to resurrect the grandioso of the original 981 design.
The shortened main tuning slide has caused me problems, as I due to my extremely strong and at the same time extremely relaxed embouchure am a "sharp" player except on piccolo trumpet. My workaround is to tune the Bb leadpipe to A. Transposing is just a matter of course for a musicologist.
I ordered a longer tuning slide, which is very easy to make, but Besson never managed to deliver on that order. Despite my not so beatiful voice, I am trained as a singer, so I just adjusted my technique. Getting the 981 even more CC’ish that way as a positive aside.
Getting longish in your eyes, getting tired in my own. Please be tolerant!
