Step 3Assembly
i didn't bother making a PCB for this because there were so few components. Everything is wired point to point matching the schematic.
Tip:
When wiring the mono jack on the one side, the sleeve and ring are reversed from the first side, not parallel. If you touch the jack and it sends a humming sound through the line your shield and tip are the wrong way round.
More tips:
Using a straight edge to draw an X on a side corner to corner is a good way to find the center of plane for drilling.
Hot glue on the inside stops the cables from pulling out of the box.
You could try to put 4 jacks in the box instead of 2 cables, though then you'd have to buy patch cables to use it, and a bigger box, and you might wire it wrong if you're in a hurry.

please be patient with me...long time player but brand new to electronics....it worked really well except the repeats all sounded like they were up two octaves, not natural like your audio examples(quite ear piercing). Could it be the capacitor? the closest i could find to a 0.05 film cap was '0.047uF/47nF Greencap Metallised Polyester Capacitor ', '0.047uF 50V Blue Chip Monolithic Capacitor ' and a '0.047uF 50 Volt Ceramic Capacitor'. (i used the first option). your help is very much appreciated. great project!

hmmm... any of those should have worked. if you connect the instrument directly into the circuit what do you hear? my delay gets a high pitch if i have this circuit turned up more than 2/3. try setting your pot to 1/4. try switching out the cap for the ceramic one. i have all the patience you need. we'll get it working, have no fear. :) what effect pedal are you hooking it up to?

hey! just wired it all together... can you quickly explain the reverse wiring (tip) on the mono jack, not sure i understand. do you mean to say that the 'earth' becomes the 'signal'? but only on one of them? thanks! cant wait to plug it in!

the first time I wired it up i accidentally reversed the wires on the input. the way i had my jacks mounted, the tip of the output was in line with the ground of the input, but i wired the gnd as tip and spent some time troubleshooting. just pay attention and you should be fine. :)
