Control volume

Does anyone know a way to access the volume level for sound outputs other than the default from a script?

Model: Mac Mini running 10.11.3
AppleScript: 2.5
Browser: Safari 601.4.4
Operating System: Mac OS X (10.10)

Something like this?

set volume output volume 100

and

output volume of (get volume settings)

Thanks DJ, but these relate to the default sound output. I want to be able to adjust the volume of other sound devices that are not set to default as I have multiple devices.
