Would you call it "guitar," "bass," "bass VI," or carrots?

Baritone Guitar.

 

In 2004, Fender issued the Fender Jaguar Baritone Custom (later renamed "Jaguar Bass VI Custom"), which in format was a combination of the Bass VI and the Fender Jaguar. The Jaguar Baritone Custom used the same string gauges and tuning as the Bass VI, but differed in that it has a Jaguar-shaped body, two pickups with Jaguar-style switching options, a fixed bridge and a shorter 28.5-inch scale length.

Hmmm, our lead feller primarily plays one of these since he replaced his tele with it about 8 months ago. I never really thought about it. Apparently he didn't give it much either, because on our CDs that were just delivered on Friday, his credit says 'guitar/keys.'

 

I'd say whichever term you go with, don't go with just guitar. It's not only more accurate, but more interesting to someone reading the notes. And who knows, if they don't know what a bass vi is, they may go look it up (or at least think you're really cool for playing an "exotic" instrument...).
Just my dos cientos....

 

This is how the cure does it. But I say hypercarrots.

Deep guitar.

 

Change it.
Call it what it is.
For those who know and care to know.

 

I like calling it something to make it look interesting in the liner notes. On Jefferson Airplane's "Crown of Creation" album, Jack Casady is credited with playing the "Yggdrasil" bass.

 

Keep it, now you're credited with two different roles in case someday that somehow matters.

 

“Bass guitar” is synonymous with the standard 4-string electric bass for most readers. Although I don’t go for credits padding, in this case there’s significant enough difference that I think making a distinction and asking for the credit to read as “bass and Bass VI” is entirely reasonable. It does no harm if the reader doesn’t care. However, there are people (like me) who do care, and like knowing details such as which instruments were used on which songs.

 

"Contra Guitar"

 

'Abomination'!

 

"Bass guitars"

 

If you don't think enough people will "get" bass vi, extended range bass.

 

I would definitely change it...

... from, 'bass, guitar'...

... to, 'My Captain, whose reverberations come mainly from Middle Earth'.

 

Silla.

JES played Silla. Or Ernie/MusicMan if you prefer.
