How you place equipment is dependent on the limits of the technical specifications of the equipment.

I tend to record one track at a time here at home. If there was ever a question of bleed from the guitar amp, for example, I would place it in another room. In my case downstairs with the doors closed. I am using software, BIAB, or others to create drum lines. Digital piano, and software bass most of the time which does not create bleed issues.

My preference is to play guitar and sing at the same time but that gets to be difficult in my home studio. If I am serious I move the vocal mic to the next room and have my wife press the record button...lol

You will find the SM57 to be a very useful mic. The ribbon mics of the type that are actually useful are pretty pricy. They really need their own mic pre.

If you are using a tube amp that requires a mic, the SM57 will work well. You will have to experiment with mic placement so you get a sound you like.

The RAM issue with a computer is a simple install that you can actually do yourself. Many here to guide you through that.

“Well…” Saint Peter, hesitated, “God’s got this girlfriend who thinks she can sing…”
