Thank you! I'm glad you think so.
About the guitar and bass tracks:
- On the electric bass parts I have recorder with a MESA Subway preamp without speaker IR impulse (I find it easy and good sounding when I try something with it).
- Electric guitars on the boss theme are all recorded from a valve 100w amp (ENGL SE) into the interface preamp. I've noticed that at least for me sounds nice. It's a no brainer. But I don't discard to use emulations. On the theme track there's a Morgan amp in VST format that delivers a nice clean in my opinion. Nowadays there's plenty of software that does guitar recording fine!
