I play in a band with a mix of electric, direct inputs: electric guitar, bass guitar, acoustic guitar with a direct. The sound man often loses the chanter in the mix. Do you have a mic that could go inside the chanter top and pick up the chanter reed? I tried this once in a store and the tiny microphone amplified every squeeze and wheeze of the air from the bag and bellows. Thanks.
Any mic placed into the chanter will pick up all air movement (sound). A mic cannot distinguish between the sounds you want to hear and sounds you do not want to hear.
Therefore, we suggest a flat response condenser mic (like the Shure SM81 or KSM137), mounted on a boom arm, and aimed at the chanter. Experiment with different mic placements to find the sound you want.
