I had a M1 Active in a Taylor and it sounded fantastic. I just got an Epiphone Masterbuilt Dread which sounds really nice. I put a M1 Active in today and it sounds really weird. It sounds out of phase and kinda muffled. Almost like from the other end of a tunnel. Im very disappointed. The B string is particularily weird. I tried raising the pole pieces thinking if I increased the signal to noise ratio it would help. Does anybody have any ideas? Dead Battery maybe?
