BTW MC, is there a big difference between both the GB and the CB?
Yes... they are sonically in the same ball park, along with the 75 watt G12H Creamback... both Creambacks are meant to be, if I understand correctly, a higher wattage version of the G12M 25 watt Greenback.
However, the 75 watt has a bit more high end than the Greenie which has that lovely mid range bark... the 65 watt Creamback is much more subdued and warm sounding... which makes it a beautiful blend with the Greenie... with that being said, some folks think the 65 watt sounds great isolated, but gets buried in a mix, whereas the Greenie will almost always shine through...

If it's any help, I think it would be amazing to have a 4x12 of Greenies and a 4x12 of 65 watt Creambacks in stereo!!!!
