Re: Tame that eefer! (Barrel/Extension Question)

Hi,
The top tenon length on the Leblanc is shorter than on the Buffet or Selmer. The barrels and bells I believe are really designed for Buffet or Selmers, no surprise there.

This results in an internal space between the top of the Leblanc tenon and the bottom of backun barrel. This increases the internal volume of the horn. IMO this results in a lowered pitch around the throat area. Proportionally less, very quickly to zero down the horn. I have ended up getting nylon washers on ebay and turning/sanding down the external diameter to get them to fit. the internal diameter on the ones I got was good. You can make them a gentle press fit or use a dot of silicone to hold them in place if you like. Backun should sell spacers a good money spinner for very little outlay.

Normally I "dry socket" my clarinets by removing this internal space, by either tenon caps or turning down the tenon. I believe this can have a fantastic effect. E.g. middle tenon top e becomes more stable and higher notes can move up in pitch. This leave a sliver of space externally at the tenon.

IMO the bell b/e becomes a bit more in tune and tone improves. Low Es on my horns as a result are almost bearable:)

I have only heard good reports about the extensions I do not own one but will try a friends in the near future.

The Backun bells are too long/low pitch for the Leblancs. I have turned down the tenon to a shorter length and "dry socketed" as above to get it to pitch. Same as above for the barell.

Feel free to ask if you want more details or thoughts about barrel lenghts.
