    Hello,

    I think my build went well. However the red LED’s do not light up or the status light near the pedal switch. The only thing I can think of is the Capacitor C9 is reversed in the the trouble shooting picture. I am also missing R19. It was not included in the parts though so I am confused.

    I have an attached picture, please help.

    thank you all.

    Justin.

    R19 is a current limiting resistor for the status light. Since you are using the foot switch PCB you do not need R19 populated on the main PCB. That being said, you will need to populate the ‘CLR’ location on the foot switch PCB (see attached photo).

    Wow, thank you! I am also a little unclear on what to populate the CLR with. Is it a resistor? If yes, what is the value of the resistor please? Thanks a lot!

    Yes it is a resistor. CLR stands for Current Limiting Resistor.  Anything between 1.8k(bright) and 4.7k(less bright) will work just fine.

    Volume and Drive top, left to right and tone lower middle. Standard layout.

    The control names are also silk screened on the other side of the board.

    Thank you for your help! It’s alive!!! There’s something very satisfying about jamming with a pedal you made. I could not have done it without you guys. Thanks much!

    Don’t stop now!

    Hurray over to the GPCB Shop and order your next project board.  I’m sure there are other great effects there that you will want to use.
