I initially wanted a Greenback for my Avatar Vintage 112 (the oversized one) but was dissuaded by some people posting that they only like GB's in pairs or quads so I ended up with an Emi Wizard. I've owned a Wizard before and it's a nice sounding speaker, but I'm finding that I'm only running my bass at 9:00. It seems my Rockytop 10 head and this Avatar cab provide more than enough low end. This being the case, I'm thinking of revisiting my initial idea of going with a Greenback. My amp is Marshall voiced and the heaviest stuff I play would be the occasional Judas Priest/Black Sabbath and lately moving towards bluesy stuff. Any thoughts?
