Whew what a tough question, ToneLabRat!
Thanks for inviting me to check this out.
Well, I have quite a few sides to my guitar processing. Sometimes I mic and use pre-amp DI's, other times I re-amp like crazy....but for myself, I like to keep things simple. I have tracks I've done for clients that have HUGE guitar tones. But for me, I'm not very fond of that. The reason being? I HATE and I emphasize HATE......when people create something that they can't pull off live. In all my years I've never done anything in the studio that I couldn't do live. From licks, to leads, to special effects, punch in errors that turned into "whoa that was sick!" to guitar tones. I've made a decent living on the two world-wide released CD's I put out (another coming soon) and the one thing people say is, I sound pretty much the same live as I do in the studio. So I like to keep that frame of mind always. People know when you are trying to be something you're not or when you try to pull the wool over their eyes. Metal/rock fans can't be fooled as easy as pop fans that think Autotune has something to do with automatically fixing their car.
So for me, it's get the tone you want BEFORE you record as the first step. Most of my recording (BA=Before AxeFx) has been done with my amps or my faithful 2101. I have gone to the extreme of mic'ing 2 complete stacks (yeah, what a day that was...but it sounded cool as heck!) and then thrown a 57 and a 421 on one cab while using the speaker sim XLR outs of the 2101 at the same time. No matter what I do, I sound like me so one day I said screw it....it is what it is. I don't mic my own stuff anymore because I can't tell the difference between my mic'd rig and using speaker sim.
The reason for that is I like to do what is called "a room within a room". Meaning, I try to simulate what happens between the mic and the speaker. You know that little pocket of air? That (along with the curve of the mic you use as well as the position for a phased effect if needed) is what creates a mic'd tone. We can do this with speaker sim and impulses. You just need to know what to listen for and how to go about it. Direct tones are just that...so direct there is no room ambiance at all. Now keep in mind, the tones of today do not use much room in the tone. They sound sort of direct, but you can just about always tell when someone mic'd up and someone DI'd. It's harder and harder to tell these days, but a mic on a cab gives you that pocket of air.
This is what I simulate with an impulse. From there, a small room impulse on top of it lightly blended in with some eq on the room and you have a tone that literally sounds more live without reverb/tail artifacts or sounding like you recorded in a big room with a wooden floor. We just want a little ambiance, not a tail or even the impact of knowing "we're in a room". This to me makes a huge impact on guitar sounds....and I've not even started to process anything yet. LOL!
(you invited the wrong guy to this thread ToneLabRat hahaha)
Ok, so let's get to the good stuff. Once I have my sound the way I want it, I'll compress going to disc. Not much, but enough to where my wave form looks consistent, yet not like a square box. A light compression taking out about -2dB of gain...but not a constant. Meaning, I may see -2dB flash up periodically as I play on the outboard compressor....it's not a constant LED of -2dB. So now I have a good signal going to disc. I don't like to color anything with mic pre's or eq if I can help it. I am using a little pre in my console, but I'm barely touching it. I try to get my sound so tight that once it's recorded, there are only minimal things that need to be done to make it fit in a mix.
So I'm ready to record. I record my tracks and when I'm done, I'll create an instrument bus and add a compressor in my FX bin in Sonar X3. (Sonar lover here, sorry Cubase and PT guys lol) I'll send the two rhythm tracks I recorded to the instrument bus and I'll take out another -2db of gain using a UAD Precision Bus Compressor. This is one of the meanest little comps I've ever used for stacked guitars. This compressor will compress my two rhythm tracks as an entity and tighten them up. From here, the room within a room sound I created is in my fx return so I'll add just enough of that on each guitar track so that it opens up a bit. I allow the room sound to pick up the spacing in between the guitars. I'll explain...
Most guys run two guitars and pan them at 100L, 100R. When you do that...you leave the middle and sides out of the mix and depending on your sound/tone, you're leaving holes in the mix. Now granted, we know we have other instruments that need to be in those gaps....but we should be able to fill the gaps a little so we're not just on the ends of the stereo field. Me personally, I never go 100L/R because it's just too wide. Most people think the wider you go in a mix, the better it sounds. Though that may be true as a first impact, the truth is, you are separating your mix. Just like guys that pan drums all over....cymbals on the left, hats all the way on the right. You disconnected your drum kit. The tighter you keep your pans (I'm not saying go narrow and lifeless) the better your mix sounds because the instruments aren't as separated, understand? Your pans in a mix are just as important as the eq you use on each instrument. Anyway...sorry....I got a zillion things I want to talk about...trying to get a handle on just 2. LOL
So we have guitars panned at say, 90 for you guys that like wide pans. It would look like this...
L100<-----Guitar------------------------------------Center------------------------------------------------Guitar----->R-100
What *I* do is this....we add in the room sound I created, and we pan it more like 70% or wherever it sounds like the guitar pics up a little more "sound size" so to speak. So it would look like this now and sound like this.....
L100<-----Guitar-------------GRoom-----------------------Center---------------------GRoom---------------Guitar----->R-100
Now, you COULD just record another guitar there physically, and I do stuff like that when I want chorus parts in a song to stand out, but the room trick allows your guitar sound to expand and is still the same sound you started with. You could even clone a track and create a HAAS delay and use a stereo imager to place the sound wherever you want it.
Here's an example of what I'm talking about with the HAAS and the room within the room trick. I also added a slight chorus on this to make it a bit more authentic. (I grabbed this backer off some site...but all the guitars you hear are mine. 2 rhythm guitars here with room within a room, HAAS delay and chorus effect. Not too bad for only 2 guitars and a crappy 2101. Lead sound is one guitar tracked in stereo using a delay and a chorus)

Ok, so we have that part...lol....one more little thing which I won't take too much time on. As I've mentioned, I beta test for quite a few companies. All sorts of software, drum products, guitar plugs etc. This is an amp I helped develop for Acme Bar Gig. We were calling it "Shred" for a while but wound up calling it "Head Case" since it has like 25 heads in it. Anyway, for this example, I used a VSTi I named "Skull Job" which of course you guys know, is the best "head" we can get.
LOL! The amp looks like this:

Now this amp sim is a lot like our AxeFxII. It has input gain and is a really nice little rig. But it still needed a little something going in, so I ran a little compressor into it and just used the thing the way it was. I used the room within the room trick as well as the way I told you I use compression. The delay and all guitar effects you hear are inside the plug. This is what it sounds like:

So that's some of the things I do recording wise. I don't use anything else to push gain or color my sound. At the end of the day, no matter what I do...I sound like me. So I try to just get the best sounding "me" I can get. Hope this helps.
