I pair it with a Hartke Hydrive cabinet, and get a sublimely crystal clear sound. Even without tweaking the EQ, it just sounds amazing, with a transparent high end and a thumping low end. The rest, is customisable.
The "character" button is the scooped sound setting in a very convenient form.
What this amp does NOT do, is dirty gain. Even with the gain maxed, you get a very mild growl.
Very highly recommended.
