there's a clean sound always present in AT 5 that you can't get rid of, or more accurately, most of us don't know how to.
After I dealt with that in another thread in regard to AT 4, Peter replied saying that he had no idea what this was (and I don't blame him for that, because it's a WEIRD problem).
So even though I don't use AT 5 (nothing wrong with AT5, but I prefer the tone in the IOS version; just a preference) I got curious and started my AT 5...and guess what, the dang clean sound in the background is there too!
And no, it's not the direct monitoring, which I never use. On my interface there's actually an on off switch for that, so it's impossible to get it wrong.
I thought, this must be the same "problem" as for AT 4, so if I sort the one in AT5 I'll sort the one in AT4.
(Because AT 4 is the one I want to use. Some of the amps sound different in different versions, etc....again just preferences.)
