And WRT the technical problems, it is MHO that Steve should ditch the guitar changes, and just stick with one (-ish -- tuning notwithstanding) guitar and run it through a VG8 or equivalent. I have a musician friend who is an absolute master of that thing, and that's what he does. He can make any guitar sound like anything, including making it sound like a bass. He says the only thing that takes some getting used to is that the tactile feedback (feeling the guitar strings vibrate through the guitar and to your fingers) isn't right -- especially when you're using it to shift pitches by non-even-multiple increments (I.E. not octaves, but something bizarre, like pitch-shifting an out-of-tune guitar to a correct tuning, which it can do). His response to that is to just practice more -- if your fingers know what they are doing, then it matters less. Yes, he's that good.
