The quick description of this is a multi-effects board where you can swap out or rearrange the pedals with a pick or a dime (or a screwdriver) by removing one of 4 set screws on the bottom. Not only for guitar but used a lot for creativity with Keyboards and Synt. http://www.effectsdatabase.com/model/korg/pme40x#links
The year was 1983, and video game culture was in full swing. Global profits from video games were in excess of three billion dollars. Corner arcades were draining the national quarter supply, novelizations about video games were being published, and companies like Coca-Cola and Purina were releasing video games. Over the following two years, video games saw their collective annual revenue shrink to just 100 million dollars. How unfortunate is it, then, that Korg released its PME 40x, a cartridge-based effects system in that fateful year of decline. The launch of the unit was rather ambitious; Korg supplemented the base unit, the “console,” with 13 effects, the number perhaps prophesizing the lineup and accelerating the doomsday clock. Some of the units are really cool, such as the Octave V, an all-analog circuit with options for 1-, 1.5- and 2-octaves down, as well an octave up, an integrated distortion and a noise gate. There was an Analog Delay cartridge, and a “Dist Wah” cartridge that does just what it sounds like.
