Thanks for the kind words man!
Yep, about half the songs on the album were tracked through a focusrite saffire pro 24. I bought it as a portable budget interface but I actually have been really impressed with how it sounds. The other half of the album including this song was tracked through a presonus firestudio.
The guitars were a Schecter Hellraiser C-7 and I think an Ibanez RG927. I decided the sound of the preamps in the Focusrite were plenty good enough so I just went straight into them with no DI box. The XLR was just there because we were recording some vocals on the same day and I just hadn't taken the mic out.
So these DI guitar tracks went into the free Ignite Amps tubescreamer emulation plugin, the TS-999. This is adding about half the gain and the LePou Legion amp sim is adding the other half. LePou's plugins are free and for metal seriously sound better than anything I've found in Guitar Rig, Amplitude, or Revalver. This then went into Redwirez free Cabinet impulses, I think it was an SM57 2 inches away from the cone/cap boundary. So the entire amp chain is completely free; looking at this you might expect I am a really cheap bastard. This is not the case, I have spent money on other amp sims, and even have a Krankenstein laying around that I could use, but I found these plugins really the best and most versatile option.
All the clean tones are Guitar Rig 5. This is really a piece of shit software, UNLESS, you replace their cabinet impulses with some higher quality ones like Redwirez or some of the other stuff that has been posted in this forum. Than you can really get some cool sounds. I am really particular to the Tweedman amp and most of the clean sounds are this amp.
