An Important point.
There are 2 phases of recording, or at least you should go through 2 phases. The first is pre-recording and this is the sound you want from your guitar. So EQ your guitar to your liking and go for the sound you want, whether it scooping mids or not. The second phase is post-recording, this is only done after everything else is recorded (drums bass vocal) and your going to mix everything together. Here is where you balance the frequencies of all the instruments to make the big picture. If you scooped the mids earlier your going to have to boost them back up in the mix, as you'll have to with the other instruments to make them blend together better.
The point of recording into your computer or console is getting the best sound possible. Don't even worry about how it's going to blend just yet. That would only be putting yourself through hell, and even if you get it to your liking. You'll have to change it in the post mix.
The post mix is where you have the best sound of each instrument and then you work on blending them together.
You shouldn't skip either step as it can result is less than favorable results. Start without the first step and you'll probably start off with a sound you don't really want, and what more can be said other than you've started off on the wrong foot. Skip the second step and nothing blends together because your frequencies fight for space or they clip.
Also Doc made a point in that it does matter what type of sound (music genre) your going for, and only you know what sound you want. So no one can give you the answers to a perfect mix, there are only pointers. Note that there are infinite ways to make a great mix, go for what you want to hear.
And yeah scooping mids without fixing that in the post mix, if you do it that way, will result in the guitar having no rhythmic qualities and just a weak sound, like SPL said.
