Re: The Globe Accordeon, video 3. Optimized, far beyond it's birth quality
I first saw that on Olav Bergflodt's boxes, from Norway. He uses a 4th chord reed as standard on his diatonics. I'd been wanting to try it ever since seeing that, then this Globe came to me with it, and I wondered if it was a unique thing until I saw yours.
I've heard those reeds were made by different manufactorers, even though they all looked the same and had the same O stamp. No telling what variables came in to play on the sound and volume of different boxes.
