Yep, the Big Muff is really good at the DG sound (not quite there, but same kind of sound), and it does sound really sweet with the Carbon Copy.
Years ago I had a Kimbara fuzz, which was a 70s reissue of the 60s Shin-Ei fuzzbox. I let someone borrow it and they lost it. Think I paid less than $100 for it, and they sell for a minimum of about $350 now. I loved the 60s vibe fuzz from that thing (think every song Jesus and Mary Chain ever recorded - they were famous users), and could kill the person who managed to lose it!
