Nuno is probably my biggest influence. I have always dug his percussive rhythm technique, even when soloing. The guy has an awesome groove when he plays.
On another note, his signature N4 is probably my favorite of all my guitars, and I have many. I'm not a fan of signature gear but the N4 has the best aspect of each of my guitars rolled into one. Natural finish, ebony fretboard, reverse headstock, 1 knob, HH pu's, location of the pu switch and knob, small body, alder, light weight, perfect upper fret access, and just right neck thickness and profile. Also, the strings are high off the body compared to other super strats. Feels more like a LP. You can really dig in.
