It sounds like you are new to all this, so pardon me if my advice is too basic.
any 2 input usb interface will do. Scarlett 2i2 for instance.
You need a DAW. Amplitude is free and will allow you to record and re amp your guitar.
You adjust input gain on the USB interface and within Amplitude
first you record your guitar by plugging straight into the interface, or via a DI first.
Then, within Amplitude you add a vst plugin amp simulator to suit.
hope this is what you wanted to know
