I assume the AKG mic you're referring to is the AKG D112? Actually, many people have had a lot of success with using these on bass cabs. Personally, I'm not a big fan of mic'd bass cabinets. If your room doesn't sound really good, it's likely to just add mud more than anything else. Also, to be honest, I've got so many ways to record my bass direct (like about a half dozen different ways) AND I'm so new to home recording that I simply haven't even started to experiment with mixing in an amplifier sound, too, yet. I'm sure great results can be had with that approach.
