I posted this video on the 'Listening Thread' the other day, of Doc & Merle Watson with their long-time cohort T. Michael Coleman on bass...

Can anyone identify this bass? I can't quite make out the name on the headstock... in a few frames it looks like it maybe has some kind of Gibson-type pickup covers. 

*video is late 1970's.

**definitely looks like Schaller M4's on the headstock.

***also appears to be a half-lined fretless.

I pick up on a Hagstrom vibe, but really the headstock isn't atypical...

Hello Edward,

That bass, I believe is a Hohner/Bartell Black Widow bass!

I believe we have a winner... that sure looks like the one.

Hey Edward ,

Amazingly John Paul Jones played one in 1972!

Well, now that the mystery is solved, or at least my own adle curiosity is satisfied, I'll just have a little fun with the thread...

Like I was saying on the other thread, Coleman is one of the few bass guitar players to ever have successfully 'sold' the instrument to a larger bluegrass audience that usually doesn't accept anything other than an upright. (trust me - I've lived on both sides) His work with Washington D.C.-based headliners The Seldom Scene, (and later, crossover band Chesapeake) put him on a national stage with it. It still isn't commonplace, but I know I get a lot less of the stink-eye when I show up with a bass guitar... I can't help but think that was aided by this guy, and a few other brave souls. 

He was also a sound-guy for a while, made evident in the lyrics to this little bit he did with the Scene:

"Some nights it feels right, the bass sounds nice and round,
There's always some fool in the back that stands up and yells-
TURN THE BASS DOWN!

Well sit down you old fool, it's not to much bass that you hear,
It's just the acoustics of the room, or that half-smoked joint behind your girlfriend's ear..."


Yeah man... that's my kind of bass player. 

...love the FOH blues  , though I know I'm guilty of being too boomy
(I blame it on the drummer).



Hendrix had a Black Widow guitar, and I got to play it one lucky day !

Well beaten to the punch. I was thinking a Hohner which sold relabeled Bartell instruments back in the 70's.

I picked up and played several of these in music stores back in the day and tried them out. Not bad instruments and I thought the fretless ones were good.
However, I never bought one, nor have I seen anyone playing one.
