I started naming my guitars in High School (around 1973 or so) and continued up until around 2 years ago. I then started buying and selling several and lost track of the names
At the risk of sounding sexist, I always chose female names. It just seemed right since I wrap my arms around them as I played them... Ok, that sounded better in my head.
Any way, yes I used to but not so much any more.
