Maybe you can pick up some info here.. AS one person remarked about the different style of blues.

You did not mention the PU configuration on your Squire. or anything about your amp.
Try a test with guitar set on neck PU, middle tone setting.
Amp setting Volume 5
Treble 6
Bass 4
if you have Reverb 2
There are a massive amount of setting you could use. And as many different sound taste.
Also there is a difference with how you play and the phrasing you use.
I think I would hold off on making changes until you have explored the possiblities of you rig.
You may check out this video {rig roudown with Kenny Wayne Shepard). this was the first video I knew to be a blues player.
