Any harmonic players out there

[mmntech]

Found my dad's old blues harp in their basement. He hasn't played it in years so I "borrowed" it and decided I'd learn to play some blues. Do we have any other players out there on ATOT that can give me some tips. What's some good resources to start with?

Also what instruments are you guys rocking? This vintage Horner in C I've got is alright but one of the reeds is stuck and I can't get it open to fix it.
