Product description:
The Archer is a versatile overdrive/boost effects pedal with amazing headroom that is designed to help you cut through the mix. The Archer is sort of a two-in-one pedal. It can be used as just a clean boost by turning the gain all the way down. As you introduce gain, it will attenuate the clean signal but there is a magical blend in between that you will find. Experiment with the settings and be careful with the output—this dude is loud.

Output: The volume control is very powerful and drives fairly hard relatively early. This allows you to hit the front end of an amp or pedal to get very aggressive or crystal clear.
Treble: The treble control is a very effective EQ that goes from dark to a very "chimey," bright tone. It's great to create that midrange clarity.
Gain: The gain also acts as a mixer control between the clean boost and the gain. Turn the gain all the way down and your output becomes the volume for all clean boost. Start blending in the gain control, and it will simultaneously reduce clean volume and introduce gain...somewhere in the middle is the sweet spot or mix of the two.
