now i know you need a preamp to plug your guitar into if you want to also plus into your computer, but i had a thought. now im probably wrong, but would the preamp in EMG pickups work for it, making it so all i needed is an adapter to plug into my computer, and not one with a preamp in it as well?
Go get your shovel.

You would need an actual guitar preamp. It has the EQ settings that shape the sound.
