Hand-turned from salvaged black walnut, this one-of-a-kind amplifier features dramatic two-toned coloration, with rich dark walnut flowing directly into bright natural sapwood at both the bell and base. The contrast feels intentional—as if the tree itself designed the piece long before it ever reached the lathe.
Across the body of the horn, tight flowing grain patterns ripple with remarkable movement and depth. Subtle chatoyance shimmers beneath the finish as light moves across the surface, giving the wood an almost liquid appearance. The sweeping grain lines pull your eye naturally through the entire silhouette, creating a shape that feels both refined and powerful.
The lighter sapwood framing each end of the amplifier gives “Sproul” a striking visual balance rarely found in natural wood. It’s elegant without feeling delicate, bold without being loud.
Designed to naturally amplify your phone’s sound with no electronics or power source, this amplifier blends acoustic function with heirloom-level craftsmanship and sculptural beauty.
