You should try it out. I know my video didn't have high quality audio so I can give you a clip with high quality audio and a comparison. http://soundcloud.com/clark-kent-job/pod-vs-darketernal-ir There you have my POD HD500 match EQ'd the same way to sound like John Petrucci (Dream Theater) Dark Eternal night. NOW: the first 10 seconds are the modeler with the IR and after that it's the original track. It's pretty much identical... maybe a bit more balls in the modeler version.
