That's a pedal steel guitar.
You can approximate it on an electric guitar with a clean tone, lots of reverb & of a metal slide! Play A shaped triads on the D-G-B strings. You can also retune to an open chord. Anders shows how to play with a slide in the Blues course.
Anders also does a great job of showing how to mimic pedal steel on electric guitar in the Country course.
Hope that helps!
