smallest volume pedal?

is there somewhere i could get a schematic to figure out how to solder what to what? i tried emailing pedal parts plus and they said check the forums. i don't know what forums they are referring to.

i think i have all the parts:

pot
drilled enclosure
2 mono jacks
dc power jack
led and barrel
true bypass switch
knob
4 different color wire in 2 ft. lengths

am i missing anything?
 
Well, schematics for stuff like this are kinda hard to come by because it's such a simple circuit, and with the true bypass aspect added to a volume pedal it's a pretty unusual beast. So the best you could do would be to jam two schematics together using a bit of brain power.

What exactly do you want this thing to do? I'll draw something up as a schematic, but often people have difficulty 'translating' that to 'solder this wire here' type instructions.
 
i want this to be as simple as possible with the componets listed above that i purchased. essentially since there is only one switch and one knob, when the thing is engaged i want to be able to control the volume with the knob. so i could mute something too by turning the knob all the way down.
 
Ok, assuming you have a 3PDT switch (which is required to implement the LED switching as well as the bypass) here's how it should be wired. The three 'poles' of the switch are all 'ganged' - meaning they all operate at the same time - sorry if any of this sounds obvious! "430R" is a 430 ohm resistor, the LED has a right way and a wrong way, google for info about LED polarity.

This diagram shows the switches in the "pot active" state.

Oh yeah, as shown there is the possibility of leaving the LED switched on when nothing is plugged in, which is bad, to rectify you need one stereo jack to implement the trick whereby the circuit ground is connected only when a jack is plugged in. Not sure how familiar you are with this kind of stuff, so let me know if any of this makes sense before I swamp you with info!
