Hi David
I've sent you an email, in regards to purchase
cheers
Dan

alternate approach
i have 2 cheap mic elements [took the mics apart]
dynamic
in parallel
they are $5 karaoke mics originally

they point directly at treble reeds
nothing needed to pick bass up
they are attached to the treble block via a coathanger wire assembly
there is very little room for mics where they really need to be
because the bass side will hit them when the bellows are closed
mine has about 2mm to spare or less

they sound pretty good actually
