Test
Use the Correct Power Supply
Make sure your power supply is 9V Center Negative
If you fry your pedal with the wrong power supply, fixing it will be time consuming and may require ordering new parts. We will replace any damaged parts at cost (no markup), but try to avoid it.
Hook it Up
Plug in a 2.1mm ,9V, center negative power supply (not included) in the middle jack.
Plug a 1/4" TS (mono) instrument cable into your guitar, and plug the other end into the right input jack on the pedal.
Plug another 1/4" TS (mono) instrument cable into the left output jack of the pedal, and plug the other end into your amplifier.
Leave your other pedals out of the signal chain for now to remove any other variables.
Test it Out
Turn the pedal's volume knob to the center position and give it a try. You should hear a clean signal when the LED is off (effect is bypassed), and a distorted sound when the LED is on.
If you have any problems, don't panic! It's probably a boneheaded mistake (e.g., reversed cables), a bad solder joint (easily fixable), or a misplaced component (a bit more challenging, but you can handle it). Jump to the next chapter for help tackling this.
Otherwise, if everything is working as expected...
