Detail 01
SRT piezo pickup with System 66 preamp
Onboard controls include volume, 3-band EQ, a midrange-frequency slider, and a built-in tuner.

Independent shopping perspective
Finished in Tobacco Sunburst, the AC1M is a right-handed concert acoustic-electric with a solid Sitka spruce top, mahogany back and sides, and a cutaway body. Yamaha describes its acoustic response as warm, balanced, and centered in the low-midrange. The onboard SRT piezo system and System 66 preamp keep volume, three-band EQ, midrange adjustment, and tuning at hand when you plug in. Hand-rolled fingerboard edges, a straight-taper neck, and the 14th-fret joint support work across the neck.
