Boss DS-1 Distortion Pedal
The amp and guitar? Fine.
The pedal... not so much.

For blues you want overdrive, not distortion. I believe Boss do an overdrive pedal specifically meant for blues, the BD series I think. Though failing that, Digitech have the Bad Monkey and Screamin' Blues pedals, both of which are superb (Bad Monkey is lighter and is made to give you a specifically overdriven tube style of overdrive, this it will effect your tone slightly; the Screamin' Blues is actually, despite the name, more of just a general all-round overdrive and distortion pedal and can even get up to near metal-like qualities, and doesn't effect your tone as much though it does mean if you were to ever use it with worse gear, it can sound pretty poor).
Try an Ibanez Tube Screamer pedal. It gives you a real beefy pushy overdrive sound.
Yeah, you can sell it...

It's not an awful pedal or anything, just far too fuzzy and modern for blues and most rock. Maybe you could trade or part-ex it for a TubeScreamer - type pedal?
