A gutted credit card reader is repurposed to become another instrument for the Alpha-Bit arsenal. All the circuitry has been removed except for the magnetic stripe reader; in its place an amplifier and a speaker have been housed in the enclosure. Slide your credit card (or any card with a magnetic stripe) and hear the data information translated onto audio. Producing sounds similar to a scratching record player, the scratch box is a fun and expressive instrument. A 1/4″ output is included (as always) so that the fun can be made even louder when plugged into an amplifier.
