........... So................ I give you a riff... and that's not what you're looking for... and then you say 12 bar blues....... Julian breaks down 12 bar blues.... annnnnnnnnd...... you say you're already experienced in 12 bar blues, thank but no thanks....... I'm confused about what you want us to give you... You want riffs.... as in... Once again from memory... this is a little blues lick I've been messing with... I mess around with pinch harmonics and hammer ons and such. I sort of derived it by ear from Good Clean Fun by the Allman Brothers... it's not the exact riff from that song... not even close really... but it resembles it.
