Detail 01
SRT piezo pickup and System 66 preamp
The guitar provides onboard volume, 3-band EQ, a midrange-frequency slider, and a built-in tuner.

Independent shopping perspective
The AC1M is a right-handed concert-size acoustic-electric built with a solid Sitka spruce top and mahogany back and sides. Yamaha describes that pairing as warm and balanced, with emphasis in the low-midrange. Its SRT piezo pickup and System 66 preamp put volume, EQ, midrange adjustment, and tuning controls on the guitar for plugged-in work. A cutaway, 14th-fret neck joint, straight-taper neck, and hand-rolled fingerboard edges focus on access and fretting comfort.
