So I was highly jazzed from finding out that the line6 aggro was included in the hd metal pack. Love that amp in my pod xt live and felt that nothing in the hd500x compared to it. I bought and downloaded the upgrade and got to fiddlin. Soon came to the opinion that the newer version seemed a lot muddier than my original- and this is just through headphones, by the way. Is there something I can adjust to get the brighter sound back? Maybe the deep editing on the amp settings needs to be tweaked? Tried somewhat with this but to no avail. Any feedback would be greatly appreciated.
