Welp... let's see...My first piece of advice is:

You will want to research something called "Gain staging". THIS IS TRE IMPORTANTE... I would nae recommend doing dis without dis.

What it means essentially is, you want to have a very low signal coming in; for a computer maybe -12db on the track.

Depending on how you record your guitar, this can vary greatly.

This purrrrticular song was done DI or "Direct In". I just plugged me strat into me splat, and den dare I was. (splat means interface)

If you do DI, I would recommend Poulin plugin for your Amp modeler, and then you can use W/E ye want fur your cabinet modeler. I use Guitar Rig 5. (The stock plugins suck, but it works for a cab modeler)

There is ANOTHER WAY!!! And I have used it too.

I use what they call an "attenuator". It is fancy word for something that lets you use high voltage amps with yoru interface so it does not burn it out.

You can't put 100 watts into an interface, THAT IS VERY IMPORTANT TO REMEMBER! ROFL

Oh, and don't spill koolaid in your tube amp.

This Attenuator will allow you to get A REAL amp sound into your DAW.

It has worked great for me.

I hope that helps. ^_^
