Rentals in Portland?

Dear Lazyweb:

I need to rent a good recording amp for August 1st to the 8th. I’m thinking a Gibson GA-20 or a ’66 Champ or something in that neck of the woods. Obviously, given my locale, the rental needs to take place in the Portland/Salem, OR neck of the woods.

Any help? Or suggestions on other courses of action? I don’t really want to buy another guitar amp, as I have all the guitar shit a keyboard player needs, but I do need something a little more highbrow than what I gots for this session I have coming up. Hook a brother up.
