How, just how? To be specific, *THAT* tone on the Derek and the Dominos 'Live at Filmore' album. I've had the album for 20+ years, but still am open mouthed and just don't get it when I really listen to it. A Strat, wah pedal, and arguably either a dual showman/Sunn solid state... it doesn't add up! A half cocked Wah always on != creamy santana like sustain, piercing attack, borderline break up - it blows my mind. I've always been a Clapton fan (Mainly in Cream, D&D and some later stuff), but he shows his genious here.
