Let's face it, secretly, we all want to be shredders (okay, sometimes, at least), but that can get old very quickly.
A very cool thing to do to get your speed fix is to throw in some chromatic runs with your basic blues scales to give the "illusion of speed." When used with taste, you can throw this stuff in, not sound like an ego-jockey, and still add some 'flash' to your soloing.
I was noodling and came across a couple of licks one day. They are both in A. I thought it would be cool to share, since I won't be laying them down to tape anytime soon (unless the Lord calls me to! He's gotta' send me a band first...)
The first one is mostly triplet hammer-ons with little "stop notes" in between. Basically, the 3 chromatic notes are the same length as the one single note (nail the triplet on one beat, basically). The last 3 notes are your run-in-the-ground blues lick, but you can end it however you like. Sorry no sound clips.

The second one I play as mostly hammer-ons again, and is very similar. It does some "overlapping" runs, though.

Yeah, I know these are basic, but they're fun, too. Thinking chromatically can get you out of many a rut, so have fun!
God bless.
