IIRC, the Fender Mustang uses an ASIO driver. To see the device requires changing the drive mode from MME to ASIO. Unfortunately, I do not believe there is any way to hear audio from the DAW when using the Mustang ASIO driver.

I downloaded the ASIO driver for my computer, and it still doesn't show an option for it.
 

 
As mentioned, I do use this amp on my other older computer, and it works perfectly. It does also do playback of the audio.

Use Imgur for pictures,, Photobucket will hold you ransom for cash..  
And actually I think you need 30 posts here to post pictures and links.  
 
My friend has a Fender Mustang.
Switch to WDM  or WASAPI exclusive mode. ASIO and MME won't work properly is you already have a proper audio interface. 
But here's a tip,,, the sound you will get sucks anyhow,, so we just use a mike. 
It seems tinny sounding compared to the speaker output. OK for putting down ideas but not for blasting out a crunchy tone. His is an older ( 5 years?)  model so things may have changed.
