Hi all. Im an absolute newbie to electronics, but I decided to try to build this amazing pedal.
If anyone has built it, Im just looking for any tips. Im reading up on all the basics, like polarity,  etc...
But are there any walk-throughs, t little things like how to attach the rotary switch, does this go directly onto the pcb, legs pushed through the holes and soldered on other side?? Sorry, just a complete newbie.
Thanks all. Even if anyone had a finished build, with photo of the wiring would be great±.

Ok, I have read quite a bit since, and at least Im getting to grips with things, a bit more understanding.
But I just have one question.. the Rotary Switch, when I fix it in place, the "pole" where the knob get attached to, seem to be very high.
Am I right in thinking that this needs to be cut down?? Sorry, just want to be sure before I go chopping it!
Thanks.

Welcome!

Switch shafts are "always" too long. It is easier for the user to cut it down than for the user to stretch it.

If it is just a little too high, consider if you can throw some washers behind it to move it back. (This almost never works out, but you could be the lucky one.)

Measure/mark three times, so you only cut once.

You really want a vice and fine-tooth hacksaw.

Don't get metal dust in the switch.

Thanks! Its really long, like at least 4 times longer that the potentiometer shaft. It is plastic though, so sawing will be easier!
Decided to get a few practice kits also, to try out some soldering, and handling the equipment etc. My father-in-law thinks it too complex for me, so want to prove him wrong as usual! Ha.

Sawing plastic is sometimes easy, and sometimes the blade gets bound-up in melted plastic. For a shaft, go easy with a hand saw. (Sawing cow-stall plastic panels gets tricky since slow hand-saw would take all day.)

Plastic shafts sometimes cut with sharp nippers, or garden-shears. It isn't neat but the knob covers it.

Since you have way excess, practice a few cuts first.

Also mark where you cut and where the knob comes to after cutting. Allow for bushing and nut, use this dimension to mark your final cut.

Well, I build the effect, and it works after a quick test. Just boxing it up now. The potentiometer shafts seem too long for the knobs also, is there a way of trimming them, or not attaching the washer/nut on the outside of the casing so they dont stick out so much? Thanks again.

In response to the questions in the forum - PCB Layout for Musical Effects is available from The Book Patch. Search "PCB Layout" and it ought to appear.

Pere Ubu and Raygun Youth? You're either a real cool kid or giving away your age  ;)

"...and weird on top!"

Yes. I am a very old little kid! Anyway, pedal worked out perfect! Hacksaw did the trick. Thanks all.
