It's rare for me to click on the Soundcloud play button and for it to actually play here, it worked on your tune for some reason. Really nice sounding raw timbres there IMO. I think your are correct, you'll be needing that Orangetree lap steel soundset if you plan to tackle that genre.
Mix sounds OK here without hearing it through Arc2 or VRM box. I liked the sound of the bass, perhaps a tad too loud in volume or needs a speaker sim of some sort, that audiffex bass speaker plug should do the trick IMO. Drums sound like they will fit into place nicely once the room is worked out. Just a bit up front in the face IMO, understandable for just being raw tracks.
Good stuff Larry from another old metal head that likes exploring other genres
