I changed my mind....If you are asking this question, the last thing you want to do is play with multi-mic'ing.
Get a 57, put your headphones loud, and move the mic starting dead center and slowly work your way out. It will go from piercing> excellent> muddy. Find the sweet spot, record 10 seconds and play back in isolation & with a mix (even if it is only a dummy bass and or Vox). Don't totally disregard isolated tracks, if it sounds like garbage it is garbage. In context is very important, but there will be moments when your guitar is isolated on the track so make sure it's solid.
If you have a hi end preamp, the 57 slays. If not, I have found the 57 sucks. Shrill and abrasive through mediocre pres, I would try out an LDC to see if it works better. Regardless, the louder you play, the more air you push, the better it will translate. That sucks, most of us have kids, neighbors, hearing issues....damn them all- turn it up to 11. Or at least as loud as your room can handle- at some point small room feedback + roof vibrations will tell you when the amp is too loud.
If possible, move your speaker cabinet into different rooms and different spots in rooms- that will make a HUGE difference. Find the tone that works before busting out the mics. Some rooms are lively, throw a small rug down in front to tighten it up if need be.
If you start getting into adding room mics, phasing issues may frustrate and crush your spirit. YMMV
