Folks used to criticize the look and sound of my Weltmeisters.. actually branded Gallota and Regal. They are very fine modestly priced instruments.
I played on them for many years..
Bubba is playing a vintage Sterling which is completely different from any current accordion with that name. They are rare as hen's teeth and sound like a million bucks. They also use a lot of air and have loose bellows compared to a modern box so you have to be a very good player to get everything out of them.
