While retaining the sound characteristics of the Series II, it offers improved intonation, especially in the upper register, and favors emission in the lower register.

Its ergonomics, also inspired by the Series Il to respond to the needs of all musicians, benefits from the latest innovations, updated for the Supreme: a new 3-point neck receiver system for better sound homogeneity, a nickel-silver tightening ring for greater density in this sensitive zone, an octave key with Teflon supports for more mechanical fluidity, etc.
Embellished with original engraving in the Art Deco style, paying homage to the age-old techniques handed down through generations of artisans at the SELMER factory in Mantes-la-Ville since 1919, the Signature alto is both a traditional saxophone and a beacon of modernity.
