It’s common to see a DJ use a turntable as a musical instrument. Physically manipulating a record while its playing produces its own unique sound, but it takes some finesse and puts strain on the delicate workings of the player when you do it. With this in mind, [Jeremy Bell] has refreshed the notion of appropriating old technology to create new sound with his home-brewed scrubboard.
Making use of a cassette tape, [Jeremy] dissected samples from the reel and laid them out in horizontal strips over rails to hold their form. The pickup from the tape player has been hacked into a separate piece that glides smoothly over these rails, giving the user the ease of control. To produce the immediate cutting effect that is less easy to perform with his device than a record player, [Jeremy] created an on and off switch which is simply a close pin covered in foil that teeters over a metal contact (in this case a coin). The end product sounds exactly like scratching a record, but better because he’s doing it with hacker showmanship. One can only image the awesome potential for more elaborate setups having multiple tape samples and the like!
There are a few different videos of the scrubboard in use on [Jeremy’s] website. He is also running a Kickstarter right now in order to turn the project into a stand alone instrument with improved features.
Thanks Omar, for telling us about this cool re-envisionment!
