Oddly, many remember this expression as a term used in describing
music i.e. This is screwed
music, or this tune is screwed... without realizing the basis of it.
In the 'old days' mechanical turntables were used to 'play' 'records'. These had an adjustment screw which allowed one to set its rotation
speed to a calibrated reference, to maintain 'high fidelity', (usually a radial pattern was put on the turntable and a 60 hz
lamp made a standing wave pattern which visually allowed a user to synch the
speed to the
lamp). The 'screw' which was actual a 'bolt', would move an internal cone, and attachment to the spindle of the drive motor, and there a transfer wheel rubbing on the inside of the
bottom of the turntable wheel, would press on it. Thus turning the screw, forced the transfer wheel to locate itself along a different conic radius, spinning the record at a different
speed.
As the 'art' of 'playing a record' evolved, the use of this 'screw' to imply a taste onto the record playback, through its
speed, became popular. Some turntables were later offered with servo (electromechanical) screws, so that
speed modification, could be encoded and programmed, for repeatable shows. It was first merely a technology, which turned to art, and then converted to an appreciation of the result, which made this term popular... then, the term... became separated and self standing as slang.
