FINAL TESTING & ASSEMBLY
After everything is in place, just plug the 3 wire assemblies into their respective headers and make sure
they’re secure. That’s it! Here is a cross-section of the inside of the completed pedal.
At this point, you have completed the full circuit as far as the electrons are concerned. Plug in a 9-volt
supply and test it out with a guitar and an amplifier.
Test the bypass switch a few times, then start turning the knobs and see if everything sounds OK. If it
works, great! If not, don’t be discouraged. See page 26 for troubleshooting info.
Finishing touches
Now, just a couple of things for the final assembly. Turn the shafts all fully counter-clockwise, then put
on the knob and rotate until the indicator line is aligned with the dot on the enclosure that shows the
zero point. Affix the knobs to each of the potentiometer shafts as shown in the diagram below.
Using a small flat-head screwdriver (no more than 0.1” / 2.5mm in diameter), tighten the set screw until
it presses against the shaft of the potentiometer and holds the knob in place.
Don’t over-tighten or you could damage the set screw. But on the other hand, if it’s not tight enough
then the knob will be prone to falling off or losing its alignment with the markings on the enclosure.
Last, just close the panel on the back using the four screws. Before that, though, grab a permanent
marker and write your name and the completion date on the inside of the back panel. This is an
accomplishment!
