I know there are dozens of threads about that matter but I'm still unclear with some things... I think of ordering a 6505, mainly to use it with irs and did a little research. I read this thread and the guy mentioned that the preamp of the 6505 is kind of compensated and therefore muffled sounding : Can anyone confirm this? Also my interface (Line6 GX) doesn't have a line input, only guitar in. Could I use this to record the Preamp out/FX send signal anyway?
