Pointing your mic toward the cone of the speaker takes a lot of the bass out of the guitar. If you want more bass, then simply inch the mic up until you get the sound you are looking for. Keep in mind that even if you do get a tone that you like on its own, once you add it to the mix, you may not like it any longer. Try to track your guitar keeping in mind how many other mid range instruments you are going to have in the mix.
Also, a good way to fatten up your guitar tone is to double track. If you do this, I recommend playing each part twice (or three times if you like) versus just cutting and pasting the second guitar part. It will be louder, but not fuller. Does that make sense?
