I’m also a Greenback and EVH Celestion guy. I can’t stand the Creamback 65’s……,,they are nasal, flat, and murky sounding to me. I find the 75’s usable, but not my preference.
I actually like the neo Creamback over both by a good margin. I currently have a pair loaded in an EVH 2x12 for a light, grab and go cab. The neos sound closer to the greenback reissue than the 65’s to me. They are clearer sounding without the high end scratch of the 75’s.
