Hello, I've got a 2x12 loaded with Greenbacks. The cabinet is relatively new and the speakers have maybe 3 hours of playing time on them @ the most? I really like the complexity of a Greenback/Vintage 30 loaded cabinet & I know a lot of others do as well. So if you have a 2x12 loaded with 8 ohm Vintage 30's & would like to give it a try or even a 1x12 that you'd prefer a Greenback in hit me up! Your speaker doesn't have to be new like mine as long as it's in perfect working order & good condition...
