x2n isn't too far from the evo tone wise, its a lot hotter though... but in the neck spot in parallel its a very smooth pickup, and if you were to wire a 3 way mini switch to the neck pickup for series/split/parallel, when in series it'll actually overdrive an amp, when in parallel or split its smooth as butter... definately gotta know about wiring if you want to do this stuff... and one solution for the jack problem could be to just buy another cable for your new guitar, and keep it plugged into it, so when you want switch at a show etc you just unplug from your amp instead lol... or you could put it on the longer horn of the V on the back, so it won't poke you anywhere, though then you'd have to figure out how you're gonna get a wire to it...
yeah, 2 x2n's is how i prefer, i run that in the 6er i built, with the bridge in series neck in parallel... and i built a 7 string superstrat with the same config but a 3 way miniswitch for the neck pup...
