This is a very nice wallpaper of an amplifier, the view here is of the amplifier controls and we can see the guitar cable is plugged into the amp.
The amp have nice controls. The knobs are black with an steel inlay and the controls go from 1 to 10. You know there is a joke about guitar amps, that the ones that go all the way to 11 will give you even more power. Because most amps only go to 10..
Anyhow this is wallpaper have an dark and almost copper fell to it. The feel I get is almost vintage or something like that. This is also a widescreen wallpaper the size is 1920x1080 so this will look very good for you that are running widescreen computer monitors also.
