A friend of me who play's guitar recently bought a Randall stack: head + 4x12"s cab. And I was amazed about the price; about 1.000 (is as much the same in $). So I reasearched about their bassamps, and I found a 200w 15" basscombo at 1.000 $. With an 9-band eq. What makes them cheaper than other brands ? Are they of lesser quality ?
