You don't wanna do it too much because it can make your guitar sound too thin and it will be hard to distinqish rhythm. How much you scoop would be a preference of style but I know Metal bands like Death do scoop their mids on recording, usually around 3-5. If you want a bold heavy sound you need to leave alittle in there. ;) Go for the sound you use when practicing, and see how it works out when you put the other instruments in. Recording is a learn as you go process.
