Step 5TEST
Lets do the first test!
Plug a guitar cable into the instrument input, and hook up a 9V power supply (battery or adapter, doesnt matter). The pedal is now powered. If the green led is on, flick the miniswitch. If you see no green led light up at all, check your green led. Its probably wired in reverse, so swap the leads and try again. If your green led works, press the momentary switch. The green led should not go off, if it does, you probably made a serious wiring mistake. If everything works, flick the switch and test the other mode:
- NO LEDS ON - The pedal is probably in the original switching mode. Stomp the pedal down. The red led should light up. If it doesn't light up, its probably wired in reverse. Swap the leads and try again. Also, try to push the stompswitch down with your finger. The switch might not actually switch because it's not mounted properly. Try raising it if this works.
- RED LED ON - The pedal is in the original switching mode. Stomp the pedal down. The red led should go off. If is doesn't, you've made a wiring mistake. Maybe you bypassed the switch somehow. Recheck the wires with the diagram. Also, try to push the stompswitch down with your finger. The switch might not actually switch because it's not mounted properly. Try raising it if this works.
If this all works fine, there is a big chance that the actual wah will work as well. Plug in a guitar and turn on your amp. Don't crack it up yet, it might squeal or buzz. THIS WILL NOT KILL YOUR AMP OR GUITAR, don't worry. Try the wah in both foot-on-pedal and standard mode. Possible problems you can face:
- buzz, and no guitar sounds. Solution: a wire is not connected. If it doesn't work in both modes, with wah on and off, it is one of the main wires coming from the circuit board, going to the miniswitch. If it doesn't work in one of the two modes, check out that mode for loose wires. If it only works when the wah is off, or only when the wah is on, check the wires on that side of the switch.
- squeal. solution: you mixed up the two wires from the wah circuit to the miniswitch. Just swap them and it should work fine. Again, if it only works in one mode, just check the faulty mode and those particular wires.
- nothing. Just silence. This means there is a shortcircuit somewhere. Check if there is any bare wire that hits another wire or lead. Also, check for mixed up wires. Again, try to isolate the problem by testing all modes.
Don't give up. Testing is always the hardest (and most boring) part. But eventually you will get it working!
