With you playing and the nature of the tune, Bruno, these comparisons are very revealing. If I had to pick one? The Bohema, probably, though I’m guessing it’s much harder to play than the Yamaha. But also, the Yamaha (your wooden one, at least!) stands up very well by comparison with these other primo melodicas. We’re lucky that we can all own a Yamaha P-37 (P-25, P32).
