Well, I played your patch with my JP6 BFR and it sounds good. (You were using a User Cab that was unidentifiable, so I just loaded Factory #43 cab which is a 4x12 Recto SM57.) I don't hear anything that sticks out to me as a bad patch. I'd tweak it a little more to my liking, but that's just because of my ears and setup. Sorry that I couldn't be more of a help to you.
Well, a second opinion is always helpful, so thanks for trying. Im gonna try monitors.
