I had (have) a SANO accordion, wood, steel reeds, bellows, and a double tone chamber ... internal mics for amplification through a SANO amp ... BEAUTIFUL sound ...
a friend of mine had the same set up ... went to see him at a gig and he used very 'treble' settings ... sounded tinny ... he asked me to sit in and I changed the settings to what I used ... he told me how great it sounded and asked if it sounded that way when he played ... I said it would if he kept the settings as I had them ... two songs later he was back to his tinny sound ... to each his own ...
