Hey gibson175, in those days I was in a band called The Nazz, playing covers around town. The rig was a kind of modular setup, with two 4101 JCM900 ix12 combos with a pair of single 12 cabs under each, and a Mesa Boogie Studio Preamp splitting the stereo sends. So it added up to 100w a side stereo, into 4 12's. Haven't owned a quad box since I was a kid! It was still kinda loud though!
