The M1 is a patented humbucking pickup with a twist. In a common stacked humbucker, the lower coil cancels hum, but doesn’t contribute anything positive to the sound. L.R. Baggs has unlocked the lower coil with a carefully tuned support that allows it to capture higher frequency resonances. As the pickup moves with the guitar’s soundboard, a body signal is created in the suspended coil that adds presence and realism to your amplified sound.
