The M1 Active takes the M1 pickup to a new level of performance and convenience. The built-in all class A electronics eliminate the need for any external preamps and makes the M1 Active compatible with any outboard equipment. And the volume control gives you fingertip access in any performing situation. Output can be up to three times that of the passive M1. This is an excellent choice for high-volume situations.
The LR Baggs M1 Active acoustic soundhole pickup uses new technology developed by Gary Garrett and Lloyd Baggs to allow the pickup to respond to the guitar's string and body vibrations. It's a humbucking pickup - with a twist. In a common stacked humbucker, the second, lower coil cancels hum, but doesn't contribute anything positive to the sound. In fact, it can muddy the sound of the main coil. In the M1 Active, the hum-cancelling coil is suspended under the main coil by a tuned support that allows it to move in three dimensions. The primary coil moves with the guitar top and creates a body signal in the suspended secondary coil. Motion is carefully controlled to add the presence and realism from the body signal while suppressing runaway feedback. This brings the M1 Active to life, with string and body sound all in one. It's like having a dual pickup system in your soundhole. The M1 Active allows you to play at high levels without feedback, and the combination of string vibration and guitar body sound produces a quality of acoustic sound unrivalled by other soundhole pickups. Ideal for both live and studio situations.
The M1 Active is easy to mount across the soundhole using two fixing screws - the tapered ends of the pickup mean that it can be fitted to guitars with soundholes of different diameters. Connection to the endpin jack socket is is via a detachable lead. (Endpin assembly and lead are both supplied.) Adjustible polepieces allow the balance of individual strings to be adjusted - although the factory setting is usually spot-on. The M1 Active is powered by a 3v lithium battery which provides over 1,000 hours of playing time. It is neatly mounted in the bottom of the pickup - a separate battery compartment is not necessary.
