I like both versions of this rack, and I think farkas's suggestions are good. One thing to consider, with the idea of getting a Disting and potentially some other stuff in here: Black Hole DSP 2 is awesome, but big. You say you're a guitar player... do you have pedals on hand? If so, you may find that something like a pedal interface module would be a better choice than a large module. No sense eating up rack space for effects you already have access to. The space and $$$ you save would leave you room for other things. (The Lo-Fi Junky might also fall into this category... if you have pedals that serve this purpose, no need to get the module.)
