Resonate multiple steel strings through magnetic strumming. Hover Ferrous at varying distances above any steel-stringed instrument to create ethereal sounds and floating sine waves. Fluctuate rotation speed by using the thumbwheel, pulse button, touch-plate or control voltage input, creating harmonic changes or a soft strumming effect across strings.
• Sine wave-like string resonance & harmonic overtones
• Pitch modulation
• Pitch bending behavior
• Pseudo feedback tonalities
• Polyphonic magnetic strumming
• Pitch beating between dominant resonant strings and the motor’s speed
• Activate higher harmonics and related fundamental pitches simultaneously
• Three small magnets provide higher-order harmonics and three larger magnets create lower-order harmonics
• Higher RPMs often lead to higher strings resonating and higher harmonic overtones
• Lower RPMs often lead to lower strings resonating and less harmonic overtones
• Dimensions: 13.3 x 6.4 x 2.5 cm / 5.25” x 2.5” x 1”
• Weight: 0.15 kg / 0.4 lbs
• Materials: Birch plywood enclosure + PCB/Fiberglass interface and disc + neodymium magnets + repurposed hard drive motor + negative space cutouts for exposed battery access.
• Controls: Thumbwheel for speed adjustment (+ on/off). Pushbutton for momentary full speed RPM or pulse. Touch-plate for pressure sensitive speed control. Control Voltage input for external speed control.
• Power: 9v Battery - Ferrous ships with a rechargeable 9v battery. The (mini)USB charging port is left exposed so you don’t have to remove the battery during charging. Some 9v batteries (9v carbon zinc & those that are less than 1300mAh, for example) may not be able to provide enough power to properly power the brushless motor.
• Assist 1: A provided threaded standoff with rubber tip can be added near the LED as a fretboard rest between strings.
• Assist 2: Four small rubber feet (provided) can be added to the four provided screws using a phillips head screwdriver, so the Ferrous can rest on strings.
