Matsumoku built in Japan, Electra Outlaw MPC bass from 1978. I bought this from the beloved and now defunct String Shop in Columbus Ohio in 1979. It was sold as a prototype as it had modifications to the pickups ala Rickenbacher 4001, toaster pickup in the neck position and the big single coil in the bridge. It comes with two of the MPC cartridges in the back as pictured. They are the phase shifter and envelope follower which I paid extra for back in the day. The cartridges could be worth several hundred dollars to the right collector. It is an all Mahogany body, neck thru with a rosewood fret board and the famous bowtie mother or pearl inlays. Frets have some wear but are still robust enough to be played as is or filed down to even the crowns. Truss rod adjusts correctly but you cannot lower the action down to extremes as the pickup guard on the bridge can interfere if you slap the strings. All electronics work as they should. It also has a brass nut and is set up with Rotosound strings which are my favorite. This thing sounds like a Ric but has a 5 position rotary switch that includes neck only, bridge only, neck and bridge, neck and bridge out of phase and neck and bridge with the neck only out of phase. Two volume controls with 2 blend controls for the cartridges. Push button switches engage the cartridges. The case was custom made at Cabbage Cases in Columbus Ohio. They are renowned for making top shelf, custom fit pro road gear for many major acts still to this date. This case was $175 in 1978 as it had to be hand made interior foam to fit this instrument. The case is still in really good shape for being over 30 years old. Like wise the guitar is an 8.5+ out of 10. It is a heavy bass. I am guessing it is all of 14 pounds but the sound is definitely thunder or funk with the tone options.
