Lower 48 only It's hard to find a load box that will handle a 300 watt tube head with out going with a custom build. This was the only one i could find at the time. i used it with my svt cl and put a two notes c.a.b in the effects loop of my svt. Sounded wonderful. It has built in passive cabs sims that you can use if you want to try that. Using stock photos for now. I'll add some photos when i get the chance.
