When I was 10 YO I had lessons & I had a 48 bass accordion. I liked that size. The Scandalli Air 72 bass Jnr. Is the same size as the 48 bass but has the diminished chord row in the bass.
The instrument is well made and sounds great, with the couplers for treble & three on the bass side this gives plenty of variety. I bought this instrument as a step up from a Chinese accordion & it was a huge improvement. The action of the bass buttons is lighter and the sound & tuning is far superior. Highly recommended. Dw.
