We are hoping to see them in May or June. Unfortunately that's the best answer I have for you. You can bet we'll be filming some in depth videos on this new amp as soon as it lands in the store!
If I buy an RA I have to sell another to fund the purchase. The similar (channel switching rock amps) I own are the ED and a Carol Ann Tucana 2. Don't really want to part with either but the RA looks pretty good.
