Thanks, I'm not completely pleased with that recording yet but, other than some preliminary mixing, nothing has been done to it... it's still in progress.
I didn't use my favorite cab setting on the µCab for that recording. There was a wire loose in Channel A (my Greenback channel) that would cut in and out intermittently, so I went with Channel B (Celestion G12-65). There's not a huge difference between the two, but the G12-65 emulation is, as would be expected, a little more mid-scooped around 1kHz than the Greenback emulation. I think it makes the heavy guitars sound more 'metal' and aggressive than I was going for, but it might work out in the end. I also pushed them a little too far forward in the mix, but I'll adjust that before it's finished.
I'm thinking about running the µCab into a mic pre before it's sent to the board. The µCab shapes the frequency response like an actual cab but a colourful mic pre can be an important part of the sound of an actual miked cab on its own. That's one part that's missing when you just plug the µCab straight in. So I'm thinking of a chain, more like this...
power amp --> load/direct box --> soft-knee compressor --> µCab --> mic pre --> reverb --> board/interface
I think that should put the icing on the cake.
