I just received a Greenline R13 for trial.
Looking down the bore from the top of the upper
joint there is a clearly visible circular gap, like
what one often observes when barrel and upper joint
are not perfectly matched, but part way down the upper
joint. Specifically, the circle cuts through the
hole covered by the throat A key. This circular
gap coincides with a change in the taper of the bore,
and, while one can usually note that change by looking
down the bore, I was surprised by the gap. Has anyone
else observed this sort of thing?

Dan,
I have a wonderful Greenline Bb....and I have a similar "choke" (not a gap, a change in bore size) at the location you have observed. It appears to be a carefully machined aspect of my clarint's bore.

And the reason would be (considering that Forest, Bob Spring, Ricardo Morales, and a few other people who make their living playing clarinets either play or have played greenlines)?
I've never heard anything really bad about them from people I know who have to use the "tools" to make a living. Some stay with the Greenline, some don't - but it's not because of anything inherently bad with it.

I tried a greenline Festial recently and couldn't detect any difference in the material. It's owner proposed the idea that, because of the nature of the substance, it doesn't suffer from the possibility (even likelihood) with wood that there will be a certain amount of movement, so the keywork doesn't go out of alignment and the thing works better for longer. Seems like a good idea to me. Is it still only Buffet who offer anything like this?

I guess you can't mold undercuts so they have to be machined...
Certainly Buffet has to be applauded for pursuing their innovation and I have never heard of a "plastic" clarinet i.e. ABS,ebonite,Resonite,hard rubber developing a crack like their wood counterparts occasionally do. Hard plastics,however, are not immune from developing cracks and from breakage. IMHO one should read claims carefully. p.s. I own a few Buffets both wood and plastic and like them all.

One of the biggest mistakes of this year for me was selling my R-13 greenline. I was trying to offset expenses and should have just
"bit the bullet" and held onto the instrument. It was very, very nice and had no mechanical problems or intonation quirks. Certainly nothing like you describe, Dan.

Brenda:
If it helps, I just love the Greenline. I've gotten many, many compliments on it. It plays wonderfully and with such a nice, even, consistent tone.
Thanks!
Lisa

A shrewd observation, Danny, I've seen it, perhaps 2 [more?] circles in the upper bores of modern conical/polycylindrical cls indicating bore modification. Pondering how these could be machined into the top of the UJ's, is your "gap" defined by 2 circles or just 1 ? On a diff. subject, have you investigated the much-higher mathematics employed by Benade, Helmholtz et al on cl acoustics [its way beyond this engr!!] ? Your former neighbor, Don

Re: Dan's question, it seems to me that he needs to ask Francois Kloc about this, does anyone have his [Buffet-B&H] contact info [phone, web-site], please. TKS, Don

Machining such grooves in the bore is no big deal with CNC machines.

I play on a greenline it's a great alternative from the real wood deal, I have a hard time dealing with cracks so I enjoy it. I honestly believe that there isn't too much of a tone difference to the reg. R 13
I haven't really noticed the gap thing though.
