Hey guys im new here and just started getting into effects, im going to start out with an EHX LPB-1 circuit, i made the pcb and got everything on the board fine, but what im confused about is where the input/output/+9v pads are on the circuit and how they are wired on a 3pdt switch for true bypass + led, any help would be appreciated, thanks in advance



Thats the layout im using

For bypass switching:

For output, the wire from lug 2 of the volume pot goes to the output jack tip. It looks like your 9v goes to the pad connected to R1 and R4. Input should be at C1.
I will quietly resist.

Thanks a lot, sorry for the noobish question, just trying to get my feet wet into effects building  :)

So that means i can use 2 mono jacks?

Take a look at http://www.diystompboxes.com/wiki/index.php?title=DIY_FAQ#JACKS for information on jacks. If you're using battery power, you'll probably want to use one stereo jack and one mono jack so that you can switch the power on by plugging into one of the jacks. Most folks use a stereo jack for the input for this purpose.

Well, this is an earlier layout of mine that was generally not intended for public consumption so, I guess I neglected to label the pads!
The above statement is correct.

The layout looks bigger than it is, once the .15uF caps are in there.....things are tight as it is.
I wouldn't change it but, some of you like to live on the edge!  ;D
