I tried this but it didn't work. One thing I did notice was when I touched the output wire (on the insulation) some of the whine went away. I wonder if shielding the output wire would help. Maybe twisting the output and G2 wire together from the switch to the board.

It's working! I'm going to let you guys in on a little secret. It matters which jack you plug your guitar into! 
Yep, I am really that stupid. Anyway, this thing is LOUD. I think it sounds really really good but is there a way to get the volume down to a closer match to the bypassed clean signal?

Thanks for the replies. I have been working late and haven't had a chance to troubleshoot until today. I checked everything again and still can't figure it out. I checked all of the pins on both chips to ground and only the pins that show ground on the schematic are grounded. I will try to take some pics.

Thank you for the reply.
I think I ma going to make the test probe and see if that will help. I ma thinking it is a bad Chip at this point.

Hello Everyone,
I decided to build a boneyard as my first pedal and so far, it's driving me crazy! I can hear humming and get volume and tone changes when turning all of the knobs but it doesn't pass guitar signal. I do get the bypassed signal when I hit the stomp switch though.
I didn't hookup the indicator LED's but I did jumper from B3 on the on/off switch to G2 on the PCB. I didn't hookup the crunch/hi-gain switch but I jumpered the pink and green wires and can turn the crunch pot and get more hum/volume. I didn't hook up the boost switch.
I have checked everything three or four times over the course of several days and still can't figure out the problem. Other than using a 2.2k for R4 instead of a 2k and a 100p instead of the 150p for C9, I used the same components. My voltages are pretty much the same as what Brian shows on page 2 of this thread with the exception of pin 1 on the LF347. I am only getting -0.7v instead of -2v

I am running out of ideas. Any help would be greatly appreciated.
