I am subject to a weird first world problem, whereby I am paranoid my 11R will fail, and therefore I need a backup. Problem is, I have tried most of the sub-Kemper/Axe Fx modellers and none of them seem to come close to the dynamics, depth and fatness of the 11R for high gain Marshally patches. Thus I have wasted a large amount of time trying to get close, but am always disappointed. I guess the simple answer is I should just buy another 11R. Not that cheap an answer though, because they aren't that plentiful here in Australia.
