As for Grand Funk, I'm sure they recorded (at least in the early days) with their live equipment, only downsized (one amp and cab instead of like 37), I can't imagine how else their live and studio albums would've sounded so spot-on identical back then. I'd give just about anything to have been around to see them live in the '70s. They're my dad's favorite band, and if it weren't for them I probably wouldn't have started playing bass when I realized guitar wasn't for me. I think Winter and my Soul was the first bass line I ever learned all the way through well enough to play in real-time. I'd totally go see them nowadays, but only with Mark.
