If you're in the market for a good harmonica microphone--and who isn't?--you might want to check out one or more of the following suppliers:

 

DELUXE VINTAGE HARP MICS is the brainchild of my good friend Ron Sunshine.  Ron and I were both street musicians in Paris and NYC during the 1980s and early 1990s; by the mid-1990s, Ron was fronting two groups, Full Swing and The Smoking Section.  These days he's the king of the hill in New York's swing dance scene:  a bandleader who blows harp and can really carry a tune.  His sideline is vintage harmonica mics, and he's just about cornered the market there.  Start with him:

You might also want to take a look at Fat Bottom Harp Mics, operated by master customizer/repairer Chuck Gurney.  Lots of major league harp guys--including Kim Wilson, Curtis Salgado, Rod Piazza, Rick Estrin, and Sugar Ray Norcia--endorse Fat Bottom.

Blow Me Away Productions, hosted by Greg Heumann, offers some pretty nifty hand-crafted mics, too, along with an innovative in-line volume control used by a long list of pros.
