Leem SB22 microphone

[LevinGuitar]

Not a bad microphone for the price, lower noise and not so bright like similar microphones. Build quality seems good, components are cheap and easy to upgrade (the capsule is quite good). Circuit is like MXL2001 with small changes, but in the biasing there are one 56pf capacitor to ground (in parallel to R6) that I did not found in other mics, any ideas of its use?

IIRC some GT microphones have a cap in that position as well
