I use it for 7 years
it is simply the ultimate in accordion. Exceptional hit, a double box and double bassoon is breathtaking, a compression of madness and finally bass that sound like bass !!!!. IT IS nothing I do not like!
I tried several models including Fratelli Crosio played for 12 years.
a quality instrument can only be so expensive ... no comment
I recommend everything accordionist to opt for this type of instrument. For the less experienced, there is the same range (fun), but cheaper.
