"The Remco Electronic Sound FX machine operates on a 9 Volt battery, weighs less than a pound (including the battery), is made of thin, hard plastic with cardboard backing [while flaunting burly tough-guy handlebars] and produces a seemingly endless array of loops, shrieks, whoops, buzzes, distortion, dirty noise and pure chaos. To take it to another level, fit it with a quarter inch output. The small built in speaker is loud for a battery operated machine, but I have heard one unleashed through real speakers and it basically can sound like an EMS Synthi; mean, angry and demanding attention.
These are becoming increasingly rare and sought after. Comes with a booklet of instucitons and dial settings for "Hollywood" effects such as: Ricocheting Bullet, Diesel Generator, Bionic Strength, Laser Beam, UFO Landing and Taking Off, Revving Moped and dozens more. (The booklet is complete, but many of the pages are stuck together. I thought about putting in the oven, but decided to leave it up the next owner so I don't ruin it!) Comes with the original box, which is in okay shape, but the unit itself is in Near Mint condition. Works perfectly."
