This is the configuration for using a Boss Gigcaster 8 (GCS-8) for audio output and guitar input on Windows.
To use the ASIO drivers you must switch the Gigcaster to
the audio mode MKT-RECORD so that it uses its own driver
to send individual channels over USB (by default it sends
the mix and uses the standard Windows driver not the Boss one).
First, install the Windows drivers for the Gigcaster, available from the Boss product support page.
Now on the Gigcaster, go to the Main Menu, push the three-line
"hamburger" icon to enter the main Menu, push Setup (gear icon)
and then the USB icon. Select audio mode MKT-RECORD. Unplug and plug
in the USB cable to make the computer mount the device with the new
Boss driver.
Connect the guitar to the front jack and turn off the effects for the guitar channel to send a clean signal (Press the Channel 1/guitar button, then Effects to turn them off - the circle icon at the top should be grey not green).
Make sure send the Channel 1 (no light in the dashed loudspeaker icon), and turn of the monitoring to hear only the processed sound from the computer (no light in the headphone icon).
The computer mix will go to the USB channel, so put that in your headphone or the main output.
