Hey, I want to be able to record home demos but it's all a bit awkward since when I do try to record, the tone always comes out a bit harsh since I've got a Shure PG57 and you can always hear background noise of some form due to being in a house that isn't very well soundproofed. I have tried just going line out from the amp and doing a VST cab sim but that often sounds pretty bad and it lags up my computer. Can anyone recommend something that does a cab simulation from outside the computer and actually sounds decent?
In before some Torpedophile says Torpedo.
You're seriously picking up background noise? I thought once you had a guitar cab at (conventional) recording volume, you could comfortably drive a bus through the same room and not get any bleed.
Anyway, other than some form of iso-cab, the Torpedo is you're only (I think) option for external impulse file loading. If you're happy to use a device's in-built cabinet simulation and not be able to load impulses, the Weber Mass, Palmer PGA-04 or PDI-03 or the recent Mesa speaker simulator would be good choices.
