Thanks guys, both recordings sound very different –
Bruno’s sounds more like a small accordion, whereas Mario’s sound like a muted (like the trumpet muter) harmonica.
Getting back to the first dilemma – how to get a good idea of the sound of an instrument without holding it in my hands..
My request for an EQ/Effect-less recording is still valid, from the ones who own the Pro36. As the holy grail of Melodica’s, I’m really interested..
