Selmer has been making clarinets as long as some clarinetists have memories. The Series 10 is considered by many not only a rival to Buffet's R13, but perhaps the better of the two. Whether or not you are team Buffet or Selmer, this clarinet is a superb player for any professional looking for a large swath of timbrel possibilities.
From the 1970 Selmer Release of the Series 10:
"Tradition and quality have built up SELMER's world-wide renown. With the cooperation of French and American artists on Engineering department, in close contact with that of SELMER USA have now achieved after several years study the new 'Series 10 Clarinet'
This model, thanks to its new proportions: barrel, joints and bell, and its different bore involves the qualities for which many clarinetists have been looking for already some time, due to the new exigences of the big orchestras regarding that instrument:
-Great flexibility and easy blowing, so much in forte as in pianissimo
-Homogeneity throughout the low and high register and especially in the middle register (G,G#,A and Bb)
-Full and rich sonority
-Correctness usual to the SELMER Clarinets
