Interesting you mention that. I have been eyeballing that new 800 head lately. Fender made a couple of small changes to it that were not in the 500, and I think it really made them a step better. I already have a pair of R115 cabs that sound awesome with several non-Fender heads I have, and I have always loved the sound of my R200c. So thinking of getting rid of one of my other heads and getting the 800, then adding a third 115 cab. I would think that would be all I would ever need, and would sound simply incredible. I would still keep the R200c, of course, because it just works for a lot of situations.
