This box is a pitch shifter and distortion -- a copy of the MXR Bluebox guitar pedal. You connect your instrument to the input socket at the base of the spine and the circuit distorts it and also drops it down one or two octaves. It's not a very sophisticated circuit, so the result is a real brutal low frequency square-wave that jumps around a lot, plus a distorted version of the original pitch. It makes a guitar sound like a malfunctioning Atari. It's a good vocal effect too -- it can make your voice go really low.
Controls (bottom to top):
Input, Bypass, Blend, Octave 1/2, Volume, Output.
Powered by 9V battery or 9V DC centre-negative power supply.
High school senior Andie Walsh (Molly Ringwald), represented by the upper voice, must choose between Blane (Andrew McCarthy) and Duckie (Jon Cryer), represented by the two lower voices. She will harmonise perfectly with one of them (octave harmony), and only one can be selected, via a switch. In the film she obviously chose wrong. Here is your chance to correct her mistake.
Circuit: MXR Blue Box. Built by Pat Kraus.
