I don't really know much blues with a wah wah pedal... but I can tell you some good blues with harmonicas that kinda go wah.

Anyway, Howlin' Wolf is important, and pretty darn good too. Led Zeppelin, The Doors, Jimi Hendrix, Tom Waits, etc. all covered a Howlin' Wolf song here or there. Killin' Floor is amazing. The Chess Box set has most of the Wolf you'd want.

I'm a big fan of Robert Johnson too, and I'd highly recommend him. If by twangy guitar you mean old beat up guitar, yeah, Robert Johnson. Really desolate, sell your soul to the devil music. Just a sad, sad black man with a beat up guitar. Died at 27. And there's only 1 hour and 46 minutes of Robert Johnson recorded, most of it's the same chord progression, and it's all amazing.

Son House. I've had trouble finding a lot of his stuff, but he's something special. Like a more powerful Robert Johnson. A Best Of collection would do pretty good.

Howlin' Wolf is Chicago Electric Blues, and Robert Johnson and Son House are the Delta Blues. There's some sort of a start.

Also, the White Stripes are really based on this type of the music, for the most part. If you haven't looked past their radio hits, do so now. Grab De Stijl and their self titled.
