Independent shopping perspective
Built around an ultra-thin carbon-fiber-and-birch top, the U581T-SPM-G is an Adamas acoustic-electric with Adamas X-Bracing and a hand-laid Lyrachord bowl. Its acoustic response is described as balanced across fingerpicked and strummed passages, with pronounced highs and low end. The walnut neck and ebony fingerboard pair with a 10-inch radius, 25.25-inch scale, and 1.75-inch bone nut. An active preamp and Custom Shop under-nut pickup provide amplified output, including a direct line-level connection for a PA system or audio interface.
