Ian left a question in the comments:
Have you settled on a DAW – I know you were a Pro Tools user for many years. Also is your M149 still your mic of choice?

Yes, having tried Logic and UA Luna I decided that I much prefer to work with Pro Tools. It may just be the sense of familiarity but I like the way it works and the amount of control I feel I have when I work with it. I don’t use MIDI for anything and understand that people who use MIDI a lot like Logic.

Regarding microphones, I love my M149 but it picks up everything and requires a very quiet room. The Earthworks mic I use live is really great at focusing on the guitar and rejecting other noise. So I have been working with the Earthworks mic and it really sounds good. I have also been using the microphone preamp in the MixPre instead setting up the Martech MSS-10. It also sounds remarkably good. So for now I am using Pro Tools and the MixPre (A/D converter and mic preamp) with the Earthworks mic. But at some point I will use the M149 and Martech again.
