I got the urge today to type "firstbass" into Google search. No, Google, I did not mean "first bass". But they gave it to me anyway. Aside from links to bands named First Bass and a couple things about a geocacher named firstbass, there were many, many posts addressing the questions "What was the first bass guitar you owned?" and "When did you catch your first bass?"
I can tell you the first bass guitar I owned: it was a black, left-handed Cort bass guitar that looked exactly like the one in this picture that I found on eBay:
Cort made or makes inexpensive training basses, and in about six months I could recognize the limitations of the instrument. At that point I purchased a white Fender American Standard Jazz Bass that looked exactly like this, except left-handed:
I loved that bass, and it got me through two bands and various other gigs. When I was in grad school in Urbana, IL, it was stolen out of my apartment.
Now, here are my twins, of the non-human variety:
I bought the one on the right in the aftermath of the theft and have used it for almost 15 years. It's a Carvin with a koa body. I bought the fretless one on the left about two months ago from Capitol Guitars in St. Paul. I don't show favorites with my human twins, but I don't mind hurting the feelings of the fretted Carvin.
I have never caught a bass.
