It sounds good but I don't think it's all that close to AC/DC. It's too round on the bottom and lower mids, not thick enough in the upper mids and not crunching enough in the upper mids.
I guess I have to agree with you guys after I listened again. Later this week I'm going to do the whole song at louder volumes. I had to push the gain up a bit since it was so quiet.
Here's another piece of a Krokus song that is similar to what I'm trying to do I guess. The gain is down a bit from the Sin City clip.
