I've always played concertinas which have concertina reeds, because I prefer concertina reeds to accordion reeds.
But I've been interested in one maker who uses accordion reeds...Frank Edgley. When I played my friend's Edgley concertina about nine years ago, I was surprised at its quick response. Though its sound was harsh and too loud for me, I've always recommended Edgley concertinas to those looking for better or responsive anglo concertinas.
I recently heard Edgley concertinas had been improved. On the plea of strong yen, I decided to buy a Edgley concertina at last.
I found a good-looking C/G concertina on his blog and bought it in March, 2011.
Layout : Jeffries layout
Reedpan : Parallel reedpan
Bellows : 7 fold bellows
Ends : Flat metal ends
Keys : 30 plastic(Delrin) keys
It's very responsive and its sound is much better and mellower than his old concertinas. Though I still prefer my Wakker's sound to its sound, I enjoy playing it very much!
Because the A and B notes in G row on the right hand side weren't loud enough, I adjusted the reeds by myself. I slightly increased the gap between the reed tongues and the reed frames. Now, they're loud enough!
Though I may sell it in the future, I will enjoy playing it for a while.
PS
I sold this concertina in October, 2011. I hope he enjoys playing it!

Another Edgley ( in C/G )

Bellows : 7 fold bellows

I bought this one secondhand in 2017. I guess it was made several years ago. It's very responsive, too.
P.S.
I sold this concertina after I had enjoyed playing it.
