I think trying to match a different kind of horn to another is the wrong direction to begin.
Sop is so much brighter than alto...just a different animal.
It would make more sense to tell us what you have played on sop...what worked..what did not...and why.
Saying you like your meyer on alt really says nothing...no more than saying i like links on tenor.
I may love links on sop or i may hate them.
Talk more about sound.
I think one that is playing a small chamber Retro Revival New Yorker replica, and maybe one that plays a similar Meyer would understand what I mean. Which made me wonder if it was better to post in the alto section
I purchased The retro revival New Yorker small chamber 6 without having heard it on the alto model I've got. I did a lot of listening on you tube mostly selmer. I had a feeling that the small chamber would fit the Conn ladyface, which is on the dark side. And I was right it is a perfect lead alto, which works well with both jazz, pop, r'nb we play in the big band
My soprano is a Borgani even more on the dark side. I play a Rafael Navarro Maestra 6* on it. With a Marc Jean ligature it is flexible. it is on the big and dark side, even though I can brighten it up
I 'm looking for a brighter lead soprano sound, but not with a pea shooter chamber, I find it doesn't fit The Borgani Vintage and it gives a audible saliva problem. I've tried both Selmer classic, Missing Link, Bari, dukoff, they where not up my alley
