I'm trying out this bass that my uncle had tucked away in his house. I was told it was made around 1969. Controls are vol/vol/tone with 2 switches that say mic 1 and mic 2. They work as a pickup selector. Chrome pick guard. Baseball bat for a neck haha. It has a massive radius. Telecaster style headstock. Not shown is a barrel bridge. The odd thing is that the pickups pick up sound from anything. I can tap any part of the bass with my finger and it picks up the thump. The thumb thing at the bottom isn't original obviously. The only words on the whole thing are "made in Japan" written on the neck plate (not shown). Could you help identify who made it? Thanks. Here are some pics
