Vintage Japanese short scale bass from most likely the 1970’s possibly late 60’s. The Raver name is a bit of a mystery but this bass looks a lot like other Teisco made instruments judging from the pick up, string retainer, finish and even the volume/tone knobs. My best bet is that Raver was an import name for a Teisco made guitar similar to the Audition name. This bass plays really nicely, being short scale it is very easy and a lot of fun to play. Pickup sounds good and all electronics in working order.
