Has anybody ever heard of a mini bass. It's a bass instrument that has a single tine that is plucked. The instrument is about the size of a box of wooden matches and has a single slider on it that changes the speaking length of the tine, thus changing the pitch. It has a plug for a guitar cord, and is made out of chrome and a bakelite type plastic. Looks like it was made in the 50's or 60's but I really have no idea. The bottom says Mini Bass, pat. pend, serial number is 159 and it comes in a little plastic case shaped like a guitar. It also has some other writing that I can't recall right at the moment. When played it roughly sounds like an upright bass. I picked it up at a pawn shop today for $20 and it's just so cool in a weird way. I'll post a picture of it later and give you the info on the rest of the writing on the bottom, but for now, anyone ever heard of something like this?
