Awsome playing, alas i dont like any of these amps much, i also think its a shame you play with such a scooped metal sound, most of the excellent articulation is nullified by the gain, maybe try a really ballsy kind of metal sound with plenty sustain? You marshall super lead will surely handle that.
IMHO its not all about what sounds best(one trick pony collection syndrome), but more about what will express the most within some style parameters. Versatility and dynamics are such wonderfull qualities.
PS Im just thinking out loud, nothing more.
Ow, and which clip is with the nailbomb neck pickup?
