Anticlock to reduce gain, clockwise to increase via a small hole I believe just inboard of the mic inlet. Bring a mini flat head screwdriver (eyeglass size) with you to work and adjust as necessary. Took me a wee while to get it just right. Also, using a quality windscreen will help tremendously. Tried mine without and the plosive artifacts were not worth the increased sensitivity.
