I have a 1976 series 1 I bought new in 76, it is used for recording now, but if the stage is big enough I still play it live. I use an Epic 4 for all the rest of my live playing. My amp is a Mesa/Boogie 400+ with 2-15s and 2-10s. but if the need rise's I have 4 1-15 boxes and 4 1-12 boxes , with a 2000 Peavey power amp, it stacks up real nice. It was dubbed THE WEATHER MAKER
