Congrats on your new guitar !
I also bought a JS signature 2 months ago. Play it every day. Really love the balance, definition and sustain. Bass is very controlled, which is great for amplifying. I play both with bare fingers and fingerpicks, from soft to very loud, and it takes it all very well. Recently a friend of mine played it acoustically in front of me which was for me a new way of hearing it. It sings and projects like crazy, especially the treble notes.
I changed the 012 strings to 011, then 010, then back to 011 which is what I will probably keep.
