I use a 1973 Peavey Century 120 into a 1976 Kustom 4x12 loaded with JBLs, and I love the sound. I know the head only kicks out 60 or so watts in this setup, but it seems to be plenty durn loud to me and everyone else who hears it. I also dig the deep, punchy lows I can dial in. Does anyone else have a similar setup? Am I doing myself some sort of grand disservice???
