Now you can test out the pedal!

Plug your guitar into the IN jack, and your amp to the OUT jack. Go ahead - pluck a string. See how it sounds. Test the bypass switch to make sure it actually does something. Tweak the volume (Boost) to make sure it works. Turn the drive (Dirt) and listen to the distortion increase.

The effect is more subtle than some other pedals, but it's there.

Also listen for noise. There should be very little. If it's very noisy, there's probably a grounding problem. Some things that may help include using a switching power supply instead of a transformer power supply (a small wall wart instead if a big one), and grounding the metal plates to the ground on the power supply.

Once you've verified that it works, you can go to the next step...
