Everything was recorded in Reaper - it is a really good value full function piece of recording software, even though I don't use it as much more than an 8 track. (REAPER)
I also used Bias FX - that is a bit of a timepit, because there is so much tweaking available with bi-amping and so on. I spent a few hours playing with that to set up a selection of AC30 type things and also to try their various tremolo setups - I could then pick those up when I needed them. The classic way to lose the vibe and feel of a guitar track is to stop playing for a bit to find out what that amp would sound like through a 4x10 instead, and then maybe in a bigger room with these Neumann mikes .... no, the Sennheisers .... a bit further away ....ah, no, wait, how about in an amp enclosure .... with a plate reverb ... ooh, that's interesting ..... and then by the time I have chased that sound rabbit down the sound hole I have forgotten what I was trying to play.
