It should work fine. Just make sure your guitar is tuned well (use tuner). If you need a sanity check play the lowest A note on your guitar (open 5th string or 5th fret on low E string) and it should be the same note, the bass guitar plays at the beginning of the track.
Now, how to make a blues scale sound like a blues is another thing. Blues scale is only a selection of notes that fit well to basic blues chord progression and work well more or less throughout the whole progression. But these notes are more like a letters of blues alphabet and blues is a language that, as all languages, starts from words.
The best way to start playing the blues is simply by learning and copying existing vocabulary of phrases, licks ect. Then as an afterthought you might think about how they fit into blues scale. Sometimes they won't as the blues scale is not the only scale that works well in blues. But to sum it up: don't "use" scales - they're not for using, they just are. Learn the language instead. And if you're not sure if something sounds right or not, devote lots of time to training your ear, active listening, copying from recordings. It will get you much further at this stage than studying the scales.
