The M1™ is for players who love big acoustic tone with high feedback resistance on any stage. Combining the natural characteristics of your guitar’s soundboard with a punchy string attack, the M1’s body-sensitive design provides enhanced realism while cutting through a loud mix.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. They unlock 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.Available in completely passive design, the M1 delivers professional amplification in minutes. Adjustable pole pieces provide balance from string to string and the 1/8” jack makes removing the pickup a snap for when you are in the studio. Install the pickup with the strapjack or use the 10’ external soundhole cable for absolutely no modifications to your prized instrument.LR Baggs M1-MAGNETIC Features:Highly Feedback-resistantAdjustable pole piecesA perfect blend of string and body signalQuiet hum-free operationBuilt-in gold plated 1/8" jackIncludes a pre-wired strap jack harness and 10' cable for no modifications LR Baggs M1-MAGNETIC Passive Soundhole Pickup.
