What about the Sappo and the Antenelli reeds? Are they still available? I had old Master accordions with them at one time. The best tone I ever had was my first Sydney Brown with the Hohner tupelo reeds but I broke several at every gig. My Bincis in my Falcon are the workhorses but lack the clarity and brightness.
Salpa reeds are not available anymore. Antonelli are, that's what Elton Doucet puts in most, if not all, of his. I think the Ciccarelli are close to Salpa, but he's become very unreliable.
Somewhat of false advertising. I buy parts from FRM. I asked Frank about his advertised Salpa reeds. He said they're not Salpa, but the company who took them over, which I believe is Voci Armoniche.
I just had an accordion made for me by Vignoni in Castelfidardo and it has Binci reeds. I was very disappointed. The sound is not exceptional, and the voicing is terrible. The bassoon is sluggish, the piccolo and high clarinet notes are weak, and response is unreliable. When playing in 2 or more registers, notes start sounding at different pressures.
