L.R. Baggs M1A Active Soundhole Acoustic Guitar Pickup

L.R. Baggs M1A Active Soundhole Acoustic Guitar PickupThe M1 Active features built-in all class A electronics, so there`s no need for any external preamps and it`s compatible with any outboard equipment. 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. The M1 unlocks 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.TriAxial Dynamic TechnologyThe hum-canceling coil is suspended under the main coil by a tuned support that allows it to move in 3 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! The support is carefully tuned to control motion in all 3 dimensions. This allows you to selectively add the presence and realism from the body signal while suppressing runaway feedback.Features Outstanding body sensitivity with great warmth and presence Class A electronics Long battery life Top-mounted volume control wheel Quiet, hum-free operation under the most challenging live conditions High feedback resistance Adjustable pole pieces with smooth threadless tops preserve fingerstylists` nails Built-in gold-plated 1/8" jack makes moving or removing the pickup a snap
