So I have An Aguilar SC500 head, a GS410, and a GS 212. Both cabs run at 4ohms so I can only use one at a time right? I want to use both cabs. My question is how would I do this and is a power amp the best way to do so? What can you tell me about choosing a power amp? Also if this is the way to go I would also like to know if I could run one cab clean and the other distorted? What do you think? Thanks for your help.
