I have two (2) flute mics, Barcus Berry Model 6100, each with the pre-amp box.
These mics fit inside the flute head and replace the cork. The mic screws into the cork.
Pretty Cool. Nice clear sound, great volume control.
I have two because I had an Eb and D flute mic-ed and swapped out the connection on stage.
NOTE: The standard Barcus Berry is sized to fit a metal modern flute, and does not fit the head of a wood flute (too small).
I had the corks on these units modified (added cork layer) so they fit the wood flute dimension.
Each comes with a cork, mic with cord, pre-amp box with controls (that clips to your belt).
These sell for as much as $400, but most are in the $250 range (Amazon, eBay, etc).

I’d like $200 each (i’ll take $375 for the pair) + postage (inquire on price). PayPal okay.
I’m selling because I use a wireless headset mic (which costs considerably more) and have no need for the BB units any longer.
