One day last week, I happened into the local pawn shop, mostly killing some time during my running around and seeing what kinds of guitars, basses, keyboards and amps might be available. I noticed that they had a double bass sitting off to one side of their display, and after noodling on a couple of acoustic guitars, decided to give the double bass a try.
The first thing that happened was, I couldn't find ANY stops, to be able to play some of the bass lines I was wanting to. So I decided to find the "fifth fret," to make sure the double bass was actually in tune. That was almost a mistake, as I didn't find the "fifth fret" until I was quite close to the body. I mean, I've played a double bass before, at a store in Indianapolis, and it was only a matter of noodling on the fingerboard, just a bit, until I had a good sense of where the stops were, relative to the frets on a guitar bass.
The pawn shop owner, a player himself, was getting a bit of amusement, from my "inneptitude" on the double bass, when I happened to notice, with my being 6' tall, where the headstock was, in relation to my height. At that point, I asked him "this isn't a full size bass, is it?" He's like "nope, it's a 3/4 sized bass," at which I laughed, and said "no wonder I was having such a time findig the stops!" So I guess the next time I encounter a double bass, and want to play it, I need to pay attention to it's height, relative to my own height, to know where I should look for the stops, so I don't try to play things way out of tune.
