LR Baggs M1 Active The active version of the M1, which uniquely reproduces even body vibrations thanks to its magnetic pickup structure. Equipped with a built-in preamp and volume control specifically tuned for acoustic guitars. You can easily obtain a stable sound in any environment, such as live performances and recordings. It can be used for 1,000 hours with one button battery! It also has excellent usability with volume control! Thank you for viewing. #fender #gibson #takamine #taylor #martin
