Personally, I can't understand all the fuss about capturing amps and combos. While in theory it's nice to be able to capture things like Dumbles or whatever, how many people actually have access to the real thing? And for most of us, even those with a few amps, we're still limited to how many we have access to. Unless we buy pre-made captures from a 3rd party.
And to be honest, although I have some really nice amps, I couldn't be bothered with all the hassle of trying to capture the sound of, say, my Musicman 212HD, then working on all the variations and tweaks and tones, mike placements etc etc. And still be limited to just what was captured unless we then modify that using digital modeling controls.
I just don't get it - when we have, in our Fractals or whatever other modeling devices we have, just about perfect models of hundreds of amps, effects, pedals, speakers, mike placements, etc etc, and can tweak them to hell and back - and they all sound fantastic, in either a studio setting or a live playing situation.
I don't know about you lot, but my ears are most definitely not what they used to be, and although I can tell the differences between presets, amps, etc in isolation in the studio, in a mix or live band situation, none of those finer points are audible.
Instead of wasting time capturing amps etc, I prefer to simply select one of the bazillion options in my AxeFX3, then tweak it and play it like I would with a real amp. When all said and done, it's the music that emerges at the end of the chain that matters.....
