Hopefully, I should be pretty well prepared for EEG with my Komplete 8 Guitar Rig 5 Pro. I'm reaching the outer limits of what more I can or should be buying.
I would say that sets you up pretty well software wise. I prefer Amplitube to Guitar rig, but both are excellent and will give you zillions of options with Strawberry.
What sort of keyboard do you have? There are zones for strumming and chords, I think you would find any thing less than 49 keys a limitation. The mod wheel controls the chord voicings, the Roland type mod lever that springs back when released does not work too well with the Evolution guitars as you want it to stay in position (unless you have three hands

) My work around is to assign one of the sliders on my A800 to this task.
