Well, it does have the 0.12uF bypassing on the rails. That's not fantastic, but it may be enough to run the thing without making distortion unpleasant. It probably does have higher distortion than it would with proper power, although I think people grossly overestimate the sort of rail capacitance you actually need for these op-amps. The 5uF caps in the input concern me as well, though. I haven't tested the 4556 but some chips don't react favorably to capacitance at the input.
Garrett - Your Guzzler CMoy has 50 ohm resistors on its output as well as filter caps on the input. It's not really surprising to me that it sounds different. You may recall that the chips I brought over were granier in their sound in your CMoy than they were in my test box as well.
