I've been playing the American cut and like it but thought I'd like to try the Signature.
For the same strength, I think the Signature is slightly easier to play. All things being equal, I'd go up a 1/4 strength for the Signature compared to the American. It also seems more "brattish" than the American cut. My guess is that it would cut through a band with less effort than the American, but overall, I prefer the more nuanced sound of the American cut and suspect it blends better. Both are solid good reeds, depends on the sound you're after. Really hope that Légère puts out a French cut for Sop Sax soon!

Legere sop reeds are fantastic!

As good as usual !

Legere reeds work great now with my soprano sax after years using them for my clarinets.

I've been playing a lot more classical soprano sax this year than most years, and this is the reed.ot choice at the theatre and with the orchestra. Consistent response, wonderful roundness in the sound, and best of all stays the same in those pesky environments that the soprano doesn't get played for long periods of time.
