Hi Colin, First, does this happen anywhere you play? I had this in a small practice room where the sound was bouncing off the walls; therefore, the mic was picking this up. I tried several things: 1- went outside and practiced - stopped the issue, but I can’t practice outside. Just wanted to see that the areas I Play may have no issue since the guitar sound carries outwards. 2- turned down the mic gain. 3- put a soundhole plug in my guitar.
