I'm looking for information on a bass I have. I'm not bass literate, so some of my descriptions may be worded wrong. Here it goes. It has the word Tennessee on the head, but there are no other markings at all. No model numbers, no stamps, nothing. It is a double neck- 4 and 5 string fretless, each with two pickups. 4 nobs, I think two are blend, but I'm not sure, its just what it sounds like when played. One switch, three positions. I can't find any information anywhere online or at my local music stores. Any help would be appreciated.
