I agree about the flat 3rd being almost as important as the flat 7th if you want a 'proper' blues scale. On a single row C box when you play in G the F note (flat 7th) gives somewhat a blues feel, but try as hard as you like ain't no way to get that B flat note, not on a single row anyhow! If anyone has figured a way around this please let the rest of us know!
if you pull it hard enough, the b will flatten out
well
if you pull it hard enough, the b will flatten out
though it will be so loud you can;t stand it
and each of the 4 reeds will probably end up flat by a different amount
but it would be noticed at any rate!
