Hiya, I've recently bought a recorder, It's a soprano I think

I've been able to play some of the notes and when I check the tuning on my Guitar Tuner all the notes are sharp
It's not important but if i was playing with a guitarist he would have to tune a half step up

it was an in expensive recorder and I think it's a design fault

Sussed it, I think :
The recorder I bought was an Aulos 205 A-E, and all the fingerings are different
So I've Bought a 205A and it now makse sense
