Recording guitars is NOT supposed to be a walk in the park. To get an OK sound is quite easy. But to get a GODLY sound is another. Now granting you have talent and want to get a good sound on record, this is where proper production values should come in. For heaven's sake, there is a myriad of badly-recorded guitar tracks in the local albums, and sad to say that they don't speak for the amount of talent that most guitarists here have.
For me, the most important thing in the signal chain is NOT the guitar, NOT the cable, NOT the mic, not the DAW, and definitely NOT THE FX.
THE AMP IS THE MOST IMPORTANT PART. Huh? But I don't own an amp. Or at least my amp is a sucky 10 watter. What about using my multifx through the studio amp? - This is the common problem. A lot of people are so used to bringing fx to gigs so most don't even know
how they sound. I mean, it's like getting a good sound on record for most guitarists is a moving target. So the studio in turn becomes another problem for for the guitarist
especially if the studio has inadequate amps for different applications.
So what's the solution? FIND A GREAT AMP FOR THE SOUND YOU WANT. IF YOU PLUG STRAIGHT AND IT SOUNDS GOOD, THEN THAT'S WHAT YOU SHOULD USE FOR THE RECORDING. As much as possible, copy your heroes' rigs if you can (not virtually, but in a real guitar and amp setup). If you like Killswitch Engage, get a Framus Cobra. If you like old school Van Halen, get a Plexi and a variac. If you like Queen, get a Vox AC30. At that, you are 80% close. Now the only thing you have to worry about is how to mic it and find the right room to record it in. If you want a drier sound, you have at leas less problems with the ambient miking, and for all you know you might not need it.
Miking is not rocket science. You have a lot of resources for that. It boils down to taste if your prefer dynamic mics like Shure Sm57, SM58, Sennheiser MD421, E609, Condensers like Neumann U87, AKG C12, AKG 414, or Ribbons like thre RCA 44B or Royer r121. Get a good mic preamp. NEVER USE A CHEAP MIXER AS YOUR PREAMP BECAUSE IT JUST RUINS THE 3-DIMENSIONALITY OF THE SIGNAL.
Snake your guitar cable from the control room to the amp and you should hear your signal from the monitors. Now if you have an improperly set-up control room then you'll just have more problems. Bad monitors = more chances of getting the wrong sound. Untreated walls = more chances of getting unwanted umphh because of the frequency dips in the room.
