Invest a lot of money on a Mic. That's the most important thing right there. Afterall , you are recording your vocals. Akg's are very good mics. So look into those. I use a bluebird Mic from Blue. But its meant for booths because it is very sensitive and picks up a lot of sound. If your going all computer, make sure you use a good recording program. Protools, sonar, cubase, etc.... Also invest in a good compressor. I use focusrite. Guitar center sells a really good presonus for about $300. And last but not least invest in a mixing and recording book. Trust, this shit ain't easy. Just because you have The equipment, it doesn't mean your an engineer. I been doing this for 8 years and I'm still learning things here n there. But ill give you quality music.
