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 new volume control gives you fingertip access in any performing situation. The M1 is 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. We unlock the second coil. This allows it to make a positive sonic contribution while maintaining the pure open sound of a single coil -- but without the hum. In the M1, the hum-canceling 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. This brings the M1 to life, with string and body sound all in one. It's like having a dual pickup system in your soundhole. And it's all passive! We've carefully tuned the support to control motion in all three dimensions. This allows us to selectively add the presence and realism from the body signal while suppressing runaway feedback. Jimmy Messer w/ Kelly Clarkson "The Baggs system is great. I can easily use the M1 without any modifications made to my acoustics and it sounds so good!" Paul Richards, Bert Lams and Hideyo Moriya California Guitar Trio "The California Guitar Trio has used a vast variety of acoustic pickups and the M1 is by far the best, warmest and most natural sounding pickup we've used. It is the CGT's acoustic pickup of choice" Brandi Carlile Columbia Recording Artist "L.R. Baggs is amazing! We just got an old D28 Martin without a pickup and the M1 sounds great, with no modifications made to the guitar. We are also using the Para D.I. preamp for greater tone control. I use the hell out of my Baggs for EQing." Zach Rogue Rogue Wave "The LR Baggs M1 pickup sounds amazing, I am very pleased with the clarity and tone. I look forward to using it when we track our next full length album."
