Wheelema, don't take this too personally, but you are way ahead of yourself. You are asking how to record an electric guitar in a studio, and you really don't know diddly about electric guitars or recording. First of all, there are hundreds of types of electric guitars, some with passive pickups, some with active pickups, and some with both.
There are hundreds of types of guitar amplifiers, which vary from little headphone amps to monstrous stage setups that would blow the windows out of your studio. There are an unlimited number of guitar sounds that different guitarists prefer, and that sound may vary wildly from one song to another. So what you've said is, "Can anybody recommend a good motor vehicle, and then tell me where and how to drive it.?"
A bulldozer? a Maserati?
Oh well, here's the short form. First, get on line and buy "The Recording Guitarist- A Guide for Home and Studio" by Jon Chappell. It's a little dated, but a good place to start. Essentially there are 2 ways to record a guitar, and sometimes both are used. There are a nearly infinite number of variations on those two techniques. The first is DI (direct insertion), where the guitar is plugged into a "DI box", which changes the high impedance (high-Z) output of an electric guitar to line level, and then is recorded directly. The other is by plugging the guitar into a guitar amplifier, and using one or more mics to record it, as you would any other sound source.
Some of the better guitar amps have direct line outs, so the guitar can be recorded both ways simultaneously. Then the sound can be blended for effect, or the DI output can be "re-amped", running the direct signal through whatever guitar amp you want, until you find the sound you're looking for, and re-recorded.
Within the last few years, "amp modeling" has begun to become more popular. An amp modeler is a form of DI box that uses digital technology to attempt to copy the sound of real guitar amplifiers and cabinets. THese boxes can then export the sound directly to a recorder, or output to a power amplifier and cabinet, disabling the cabinet model, and be recorded with microphones.
Now we get into opinion, which varies a lot, so these are mine, although I try to give room to differing opinions. Most engineers, in a perfect world, would prefer to use the right guitar amplifier with the right sound, in a good room, with a mic in front of it. Open backed cabs are often recorded with 2 mics, one in front, and one in back. Often, a more sensitive mic, called an ambient or "room" mic is used, backed off a bit, to capture the reflections of the sound off the walls of a hopefully good room. The classic technique is to put a well made cheap dynamic mic right up against the speaker grill, just off center, and move it around until you get the sound you want, looking for the so-called "sweet spot". Shure SM57, an $80 mic, is a favorite of many people for this, but people will recommend many, many, other mics for this.
Guitar is not often recorded DI, as only the better studios have a selection of amps for re-amping, and often the guitarist can't play properly while listening to a "dry" track. For this reason, DI recording is often done from the direct line out of a guitar amp, so the guitarist can hear the sound he expects to hear from the mic on the amp in his headphones, but the engineer gets the unprocessed track he wants to do whatever he wants to with it.
Regarding modelers, the jury is still out, but many people love them, and many people hate them. Regarding guitar amps, there are "clean" sounds with less distortion, and "dirty" sounds, where selective distortion is used on purpose as an effect. For many years in studios, Fender and Vox amps were the standard for clean sounds, and Marshall was the standard for dirty sounds, and many of these amps are still used and highly prized. Mesa became more commonly used for distortion in the 80's, and there are many other offerings from Soldano, Line 6, Crate, Ampeg, Peavey, and others. Personally, when it comes to amps, I'd rather have a Vox and a Marshall, but that's just me.
The good news is that recording studios usually use smaller amps, intended for practice or small gigs, because huge sound is not needed or useful for recording. Usually 30 watts is plenty, and many big time rock albums have been recorded with wussy little amps, such as a Fender Princeton. Personally, I use a modeler, a POD Pro, run into a Carver power amp, then to a Marshall cabinet, then mic'd. I also use a Fender Princeton, and believe it or not, a Crate MXR15 (the only Crate amp I've ever heard that did not sound like shit).
One of the problems with distortion from combo amps (amp and speaker in the same enclosure, rather than separate), is that to get really good distortion, the amp has to be cranked way up, which can get too loud in an enclosed space. The bigger studios put the amp and mic in another room. For small studios, the "monster-in-a-box" can be the solution. The amp is placed, with a mic, in a plywood box lined with carpet, and bolted shut, so it doesn't annoy the neighbors or blow your head off.
Aside from the amp lines above, the most popular modelers appear to be POD Pro XT (I find the cheaper floor model too noisy for recording), Johnson J-Station, and
the Behringer V-AMP-2, which also comes in a cheap floor version and a rack mounted unit. Sorry for the long post, but this is recording electric guitar 101. I hope it helps.
As suggested above, the short answer is let the guitarist bring whatever amp he likes, stick an SM57 in front of it in a well treated room, find the sweet spot, and record it.-Richie
