The bass tone on Manfred Mann's Blinded by the Light. Would that be the classic Fender/Ampeg tone? It's deep, fat, growly, and woolly... to me, at least.
Here you go. I'm kind of pressed for time, otherwise I'd actually go and watch it myself (it's a live clip and very well may show what he's playing). I'll have to check it out later, though.
