It Is a "Tenor Bass"

I got this when I was 15, thought it was a 'mini bass' tried to string it up as such, could never get it to tune right, forgot about it for 15 years, fastforward to a month ago and i was reading about tenor guitar, I loved the sound of it, and then digging in the storage I found my 'mini bass' and it looked just like the tenor guitar I was reading about...measured and it has the same scale (23"), too short to be a guitar, too short to be a 'short scale bass' but it has bass head tuner parts, wtf?

Tried stringing it as a tenor guitar and it *worked* and had a really neat sound, but it wasn't right....so I got the bright idea to use the top two strings from 4-string bass and the two low strings from guitar.....so as to tune this like a tenor..one octave lower...a tenor-bass.

I have never heard of one, but it sounds AWESOME. I love it because I can play some incredible bass-like melody, and I can do lead guitar work (normally I shun lead work on a 6 string, strings too close together).

I'll have to get a video of what this thing sounds like. And I will absolutely have to buy a real tenor guitar now,
