yes it can, and its a pretty good one too.
1. place it after your od/distortion pedals.
2. set all the sliders flat (in the middle notch), and set the volume on the GE7 higher than your unity level.
there you go.. step on it for a clean volume boost.
i suggest boosting the high mids a little as well to help your drives cut through better in a band mix.
hope this helps.
