Easy Vibe Mod? Did I do it?

Hello friends!  So I've been working on modifying John Hollis's Easy Vibe project to use a 3pdt switch and wire up to battery and power jack instead of requiring a millenium bypass. 
I've been trying to combine this project : http://www.geofex.com/PCB_layouts/Layouts/easyvibe.pdf

with this wiring diagram : http://2.bp.blogspot.com/-ri99J7p2Qtk/UQLVg_tSwrI/AAAAAAAAB10/G4YO6mPlceY/s1600/switch_lo_3pdt_tb_dcjack.gif

...and ultimately this is what I came up with,




but then i hit a wall with the board output.  I'm sure it's all messed up.  This is my first ever attempt to do this so I would love it if someone could take a look at my design and tell me whats wrong (or whats perfect... your call). I could really use the help.

Keep on keepn on.

Forgive me if my memory fails but I thought I recalled from your other thread that the two far sides of the board were both grounds.

You'll want a current limiting resistor (CLR) on that LED. A couple options, I show it here between switch and cathode.

I think your PCB "in" looks good but if I have identified PCB "out" it needs to go to the switch as well.

The out jack tip goes to the switch and the ring goes to ground.

Hope I got it right, hopefully someone else will look it over soon. Good luck!

when you say the output jack ring goes to ground... do you mean it goes to ground on the board? like the rightmost hole that i currently have nothing in?

Also, that all makes more sense. thanks for helping!
Keep on keepn on.

OK so I modified my plan and wired it up and got LED 6 lighting up right off the bat, and when plugged into an amp it makes a weird pulsing noise.   This is how I wired it up.  Is this right?  ANyone?

Keep on keepn on.

I think that's what I mean  :P Sorry, I can't wrap my brain around those terms, ring and sleeve. Tip makes sense to me but my own labels for the rest are kinda pornographic. Anyway, try to picture the sound flowing from the tip of the input jack to the switch, then from the switch to the tip of the output jack. That's about all there is to the signal path, all the other tabs on the in/out jacks are grounded, either by wires or a good solid contact with the enclosure. The extra tab on the in jack that we like to hook to the battery ground is just there to break/make battery ground connection. It's probably stuff you already know but I'm trying to break it down in a simple way just in case it helps at all.
