About he Builder (from Wikipedia):
Electra was a brand of electric guitars and basses manufactured in Japan and distributed in the US by two companies owned by brothers: Saint Louis Music (SLM) and Pacific Coast Music in the 1970s and early 1980s.
Unlike most other brands of imported guitars which were sourced from a single manufacturer, Electra guitars were ordered from all the Japanese factories and distributors. As a result, early models especially vary in details and quality. Later, as all models came to be made by Matsumoku, Electra guitars offered high quality at competitive prices. However, the brand never entirely lost its association with inexpensive 'copy' guitars and the brand name was transitioned to Electra Westone in 1984 and Westone in 1985. The same qualities make them popular among collectors today.
About the Guitar:
In 1976 Electra introduced a series of MPC (Modular Powered Circuits) guitar models featured a pair of cartridge slots in the guitar body, which allowed effect modules to be plugged in and controlled from the front of the guitar. Today the unusual thing is that the effects are on board, but even offering electronic effects to consumer musicians was fairly new at the time and offers an interesting alternate way to do it. There were a total of 18 guitar models which carried MPC circuits. The most notable was the Super Rock, which was a Les Paul copy. There were 12 total MPC modules offered.
This is the rare Leslie West Signature model X120. It features a solid mahogany body, 2 open coil black Super Magnaflux pickups, rosewood fingerboard. This double cutaway guitar can be best described as a modified Les Paul Jr. This was also the only MPC that came with a little light to tell you the effects were on or not.
