Shred? I doubt it. Play some raunchy leads from time to time? Sure. Like his drumming, I always felt his lead guitar work left me wanting for more. Not that it was bad, but it always felt left in the middle between 'could have been something special' and 'competent to decent'. He to me was easily the best musician in the Beatles and was a monster bass player. I'll be crucified for this, but I think he could have easily been better than George on the lead guitar too, if he was left to concentrate solely on that aspect of his playing. He was definitely more rock-n-roll than George (Taxman, Back In The USSR, Good Morning Good Morning). He had some great moments in his solo stuff too, but its late and i'm not getting deep into that right now. All in all, he probably could have been a shredder, but as it stands, not quite.
