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. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0958\/6609\/3943\/files\/Screenshot_2025-06-20_at_13.53.29.webp?v=1780601391\" alt=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eWhat it can do\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSine wave-like string resonance \u0026amp; harmonic overtones\u003c\/li\u003e\n\u003cli\u003ePitch modulation\u003c\/li\u003e\n\u003cli\u003ePitch bending behavior\u003c\/li\u003e\n\u003cli\u003ePseudo feedback tonalities\u003c\/li\u003e\n\u003cli\u003ePolyphonic magnetic strumming\u003c\/li\u003e\n\u003cli\u003ePitch beating between dominant resonant strings and the motor’s speed\u003c\/li\u003e\n\u003cli\u003eActivate higher harmonics and related fundamental pitches simultaneously\u003c\/li\u003e\n\u003cli\u003eThree small magnets provide higher-order harmonics and three larger magnets create lower-order harmonics\u003c\/li\u003e\n\u003cli\u003eHigher RPMs often lead to higher strings resonating and higher harmonic overtones\u003c\/li\u003e\n\u003cli\u003eLower RPMs often lead to lower strings resonating and less harmonic overtones\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0958\/6609\/3943\/files\/Screenshot_2025-08-27_135218.webp?v=1780601504\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch3\u003eTips \u0026amp; Tricks\u003c\/h3\u003e\n\u003cul data-rte-list=\"true\"\u003e\n\u003cli\u003e\n\u003cp data-rte-preserve-empty=\"true\"\u003eIRON CONTENT: The results between instrument to instrument will be different based on specifics like string thickness and string iron content. The more iron the better! Some cello and violin strings have low iron content, so less movement. \u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-rte-preserve-empty=\"true\"\u003eSTABILIZATION: When Ferrous is held close to the strings of an instrument you will feel the strong magnetic pull. Try to avoid contact between the disc and strings through practice and use of the provided accessories. \u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-rte-preserve-empty=\"true\"\u003ePITCH ALIGNMENT: As the disc speed comes into alignment with the resonance of surrounding strings, you will sometimes hear two pitches beating against one another before sliding\/bending into place, resulting finally in a swell in volume and greater string vibration. This can be happening to multiple strings simultaneously. \u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-rte-preserve-empty=\"true\"\u003eGUITAR: By holding Ferrous 90° to the neck of a guitar, you can use your ring finger and pinky to modulate speed with the touch-plate below. To do this, set the RPM slow. Additionally, one stabilization method for guitar is to rest the thumb and pointer finger on the outside edges of the fretboard. This acts as a way to ensure proper distance between the strings and rotating disc. \u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-rte-preserve-empty=\"true\"\u003eELECTRIC GUITAR OR BASS: When using Ferrous with an electric guitar (or other instrument with pickups) the preferred placement is above the fretboard. Keep the rotating disc at least 5” away from magnetic pickups to ensure less of the motor sound mixing with the resonating string sound (unless this is a desired effect). If Ferrous is placed near guitar pickups you will hear the heavy sounds of spinning magnets and the motor with the resulting pitch based upon the disc’s RPM. Hold Ferrous near (but don’t touch them!) magnetic pickups to hear bass-heavy distorted beating of the magnets rotating. **Never touch magnetic disc directly to pickups because this can damage\/de-magnetize them!\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-rte-preserve-empty=\"true\"\u003ePIANO: When using Ferrous with exposed piano strings, the magnetic pull can cause the rotating disc to come into contact with the strings causing a loud buzz. This can also happen when the resonance builds to such a degree that the strings vibrate far outside of their normal bounds and contact the underside of the Ferrous. A helpful method for stabilizing height is to slightly protrude the thumb and pointer finger past the flat bottom surface of Ferrous and rest them on the surrounding strings. A better method is to use the included rubber bumpers. To attach them, remove the four silver screws and place the rubber feet over the holes with the \"cups\" facing upwards, one at a time. \u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-rte-preserve-empty=\"true\"\u003eCONTROL VOLTAGE: Place the bumpered Ferrous atop a stringed instrument (making sure the bumpers are on the strings) and plug in a control voltage (0-9v) to control the speed with a voltage sequencer, for example. You will hear the slew (ramping up and down) of the RPM when there are changes in voltage between steps. It could be useful to start with a slower BPM on your sequencer or modulation source until you get a feel for interaction. Interesting results can be had with large or small jumps in voltage. Results depend on many variables, like what instrument is being used, how the strings are tuned, how far apart the strings are, etc. It can be fun to use a keyboard that sends CV to play the notes and harmonics. To do so, search for the notes on the keyboard that provide interesting interactions. You may hear resonances build and settle into place that sound somewhere between a pitch bend and slow envelope attack. \u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-rte-preserve-empty=\"true\"\u003eVANZANDT SANDWICH METHOD:  \u003cem\u003eUse eye protection!\u003c\/em\u003e Take two or more earth magnets and sandwich them around an object that is not easily resonated (a metal table leg, a cardboard box, a cymbal, a lamp shade, an aluminum bowl, a steel tank, etc).
