I just picked up my bass after years of it collecting dust and the only amp I have left is an old Sunn Concert head that I don't know anything about. This thing has little to no information on it, about all it says under two jacks on the back is Max output power 200W. The front is simple with 4 knobs, two inputs ("brite" and normal, a red brite switch, and the power switch. I'm thinking about picking up a cab that will work with this amp OR in the event this head turns out to be fried I can use it with something else in the 200-400W range. There is no info that I can find about ohms...nothing I could find by searching except one pic that has this head sitting on top of a slave head and an assortment of cabs but I'm pretty much lost with this thing. What would you look to pair this amp up with?
