Also a sidenote, but imho, @ColdFrixion, whether Sneap's profile sounds "like a real amp" or not, there's quite a difference between the profile and amp. Maybe even bigger than I'm used to with my profiles and the congestion issue imho just listening on phone with cheap headphones. It's congestion plus quite a difference in gain..
