B.B. King has his guitars Lucille.
I have a G&L SB2 (for all intents and purposes, a Fender P-Bass) named Isadore.
You?
(I suppose I’ll be the first to get this one out of the way…) Well, that’s a rather personal question, now isn’t it??
Thenkyew, Thenkyew…
now…
To be perfectly frank, I didn’t pay enough for my basses to give them names. One of these days, when I have more than a thousand dollars to spend on a bass, I’ll probably name it…but until then, to me, they’re just Fretted and Fretless.
Yes, I can sometimes hear them weeping in the dark, but it’s their own damn faults!
My Alvarez acoustic is Stephanie. My Kentucky blue and white Strat is Chelsea. My mandolin is Lucy.
Dr. J
Call me unimaginative.
I call them:
The solid-body
The hollow-body
The acoustic
Hey, I had a cat named ‘Cat’ and a snake named ‘Snake’, too, all right?
While I may be quite imaginative in other areas, I’m rather uninspired when it comes to naming my guitars. I just refer to them by the name of the manufacturer, since they are all made by different companies. So, I have the:
Fender (though sometimes I refer to it as the “Strat”)
Parker
Washburn
Yamaha
Of course, if I ever buy another instrument by any of these companies, my carefully considered naming scheme will be thrown into complete disarray. I guess I’ll cross that bridge when I come to it!
I don’t have my own instrument, but if I ever do, I imagine that “Beaulah” or “Bertha” would fit nicely.
Did I mention that I’m a tubist?
I call my midnite blue strat my “chevy truck.”
I call my Yamaha my “Piece of Shit” and my Ibanez my “Other Piece of Shit”.
Surprisingly I like my Yammy bestest though. Bought 2 guitars with whammy bars and have regretted it for the last 3 years. So they are both POS in my book.
My Black Strat. It’s Mexican made. I ought to find a really kick-ass Mexican nobleman’s name to give to it.
My viola is named Violet. Not horribly imaginative, but hey, I play the viola for pete’s sake!
I named my bass Tia Maria, but I sold her. 
Happy
I have a pair of conga drums that my neighbor has named Sheila and Bobo, but I call them my congas. My basses are called, unimaginatively, my Carvin, my Cort, and my acoustic.
I play drums, but only really care about my snare drum, (which is pretty much the “main” drum). I change its name depending on what girl im interested in at the time, right now it’s “Anna”.
The violin I used for three years in high school was “The Red Hot Chili Pepper”, because of its deep reddish-orange color.
I miss it.
I named them “MIDI Channel 1”, “MIDI Channel 2”, MIDI Channel 3", etc, etc.
I’ve got far too many keyboards to name them anything I could remember.
My tenor saxophone is “Snowball” and my piano is “Li Po.” One flute is “The Honorable Venustiano Carranza, President of Mexico,” and the other one doesn’t have a name. My cornet is “Theodore.”
My electric that I Frankenstein’d out over the course of the Van Halen 80’s I call “The Beast”
My Strat I call “the Strat” with minimal sentimentality - I think it plays great but there is not much connection
My main acoustic is a Taylor 812C (concert size, rounded cutaway). It is my all time fave guitar - yet I only call it “my Taylor” even though it means so much more to me - I should give it a better name…
My cheapie Martin 12 String (yes, they exist) I just call my “Martin” but, as with the Strat, not with the same connection as my Taylor.
Hmmm, I gotta name my baby.
I love my Fender Jazz Bass, but I beat on it too often to give it a name, lest I feel too much sentimental attachment with such an abused creature.
Upon reading this thread I have dubbed my cheapo supremo Samick acoustic guitar “Dusty” since I hardly ever play it.
