I'm looking to make a new purchase, nothing spectacular just a budget head and cab to do my bass justice. I think ive found my head, the behringer BX4500, the price is right and its good quality. However, there is also the GK backline 600, roughly the same price only i havent tried it. How do the two compare? Are there any other heads for about that price that are worth looking at? Now, this part of my question is more important. I need a cab to do my amp justice, so what should i look at/for? I would prefer a better quality 8 ohm over a poorer quality 4 ohm, that way i can get another cab later. I also would prefer Solid state, for now at least. What are some good budget cabs, and more importantly, what are some things to look for in a cab? I play a G&L L-2000 tribute, and i like to play rock/metal thanks!
