I've always thought that Celestion Blackbacks are boxy and cold compared to Greenbacks, and they are. But they're also have much better dynamics and I've begun to realize that the additional punch is almost necessary for 70s Hard Rock. I will be discussing this much more in detail in coming videos. And I'll compare them to Greenbacks as well.
