With one band we had a guy who helped us load and unload whenever and wherever we were playing in the 70s. He would efortlessly carry out a full sized Fender Bassman cabinet in one hand and a full sized Bandmaster cabinet in the other hand. We had it good!
Circa 1979, I used to carry my Univox (~80lbs) combo in one hand and my guitar in the other. It wasn't effortless but it wasn't horrible. But my "twin" (found next door one place we lived) could hoist the Univox up over his head with one hand.


... now with all this internet around i'll check out the venue and bring the Rumble if there's more than 3 steps
