I've returned the amp and a new, different one is on its way. I just wasn't warming to the high-gain character, it was a bit too smooth and bland/generic, not enough "presence" and rawness for me. I was surprised a bit, and I'm suspecting that the 60 and 120 heads must sound different (tighter, drier and brighter) than the studio. The studio was good at getting sounds such as Petrucci on "Train of Thoughts" (the darker distortion sounds), or Amon Amarth on Thunder God. I'm more into guitar sounds such as Five Finger Death Punch, Hammerfall, George Lynch, Arch Enemy, Megadeth etc.
NAD coming up soon, again!
