I've come to view Petosa as somewhat of a marketing company over the years. Maybe 20-25 years ago I was very interested in their AM-1100 at the time. I requested information and the packet they sent me was unreal. 8x11 photos of Dick Contino with his Petosa, half a dozen letters of recommendations from Doctors that bought the accordions, pictures in movies that had a Petosa, you name it. It was an inch thick. It was very alluring.
I managed to run into an old accordion instructor a few years later and he told me that Petosa accordions in the 1950s used to be reasonably decent. They would source their own reeds and build everything in their shop. He said that all stopped years ago and they basically just rebrand other accordions. He told me every time he sees somebody with one he asks to try it out and he said he's never found a single one to be even acceptable by his standard. Mind you, he's an Excelsior guy through and through. And a brilliant accordionist.
I also became acutely aware in researching brands of statements from what I assume are paid sponsors like Frank Marocco and Dick Contino. There are quotes from Frank Marocco about the Petosa being "the best accordion I've ever played" but then you can watch a video in which he's playing Victoria accordions now where he says, yep, it's the "best accordion I've ever played". Not placing any judgement or blame on them, because if I were as gifted an accordionist as either of them and if somebody gave me a $11,000 accordion and asked me my thoughts you better believe it would be the BEST ACCORDION I EVER PLAYED.
Even now, there is no website like Petosa's in our little accordion world. Beautiful pictures, great videos of every accordion played by excellent accordionists in every style to cater to any type of listener, a monthly newsletter that I still receive, etc.
Compare that to Victoria's website where getting any kind of detailed information about an accordion was always a chore. Maybe that's changed as I don't visit them often anymore.
I think the Petosa guys are competent and passionate about the accordion. They've been in the business for generations now. I just think it's a little overpriced and overhyped for what you get in this day and age.
Just my opinion and could be 100% factually incorrect.
