Ferrous Spinning Magnetic String Resonator

ExperimentalAcousticPolyphonic

$225

Imagine holding a tiny whirlwind of magnets over your guitar strings, watching them dance without a single pluck. This spinning magnetic resonator, born from a collaboration with experimental artist Evicshen, uses a repurposed hard drive motor to whirl a disc embedded with six neodymium earth magnets—three small ones coaxing high-order harmonics, three larger for deep low-end resonance.

At just 5.25 x 2.5 x 1 inches and 0.4 lbs, it fits perfectly in your hand, with birch plywood sides and rubber standoffs for stable placement on pianos or harps. Hover it half an inch above steel strings on guitars, basses, dulcimers, or even zithers to excite polyphonic swells and sine-like tones; slow the RPM via thumbwheel for bassy throbs, crank it fast for shimmering highs. Tweak speed with the pulse button for strums, touch plate for finger control, or 3.5mm CV input for modular madness—a yellow LED lights the strings below, and distance fine-tunes intensity. Powered by a rechargeable 9V battery with exposed USB port, it outputs mono audio and headphones while dodging pickups by keeping 5 inches away.

Players are already hooked on its otherworldly feedback and harmonic shifts, calling it a game-changer for live improv and texture layering, though some note it shines brightest with strong steel strings.
