I've heard a lot of good things about Scumback Speakers, that they're far superior to the Chinese Celestion Greenback reissues - but I've yet to actually hear them, so I was interested to see this today, and figured it was worth sharing: If the difference they make with the little Roland amp used for this demo, I would lurve to hear a set of these in a 4x12!
Plus, check out the fearsome mullet on Vinni the reviewer...
