Wiring Diagram
(at the top)
"I" - input jack tip
"O" - output jack tip
"G" - 2 x ground connection for jack sockets
(on the left)
"+" - +9v connection for DC socket
"G" - ground connection for DC socket
Connect the footswitch like this. That's the LED on the right, connected to "+" on the PCB through a small resistor, I use a 4.7k resistor. The positive LED leg connects to the resistor. "G" on the PCB is the ground connection.
This is the "anti whining" connection. It grounds the LM567 oscillator when the pedal is bypassed, preventing audible bleedthrough from the oscillator. You might not need to use this connection if yo ucan't hear any whining!
"OJ" and "IJ" at the bottom are connected to "O" and "I" at the top. This makes the wiring to the jacks a bit neater. You can connect the footswitch directly to the jacks if you prefer.
Pic of the inside of the finished pedal. Notice the electrolytic capacitors are bent over and laid flat, this is important to fit it in a 1590b case:
Schematic
Additional Instructions
Lay the electrolytic capacitors flat before soldering, as shown in the above picture.
Remove the dust covers from the "DRY" and "VOL" pots. This will make extra room for the top mounted jacks (important if using a 1590b). Re-use one of the dust covers as a shield between the dual gang pot's body and the PCB. You'll probably have to cut some of the dust cover away and they can crack easily, so try to use lots of small cuts. It doesn't matter too much if it cracks, it just needs to lift the pot a bit.
Elevate the other 3 pots before soldering so they are at the same distance from the PCB as the dual gang. These pics are of the old style PCB but the principle is the same.
I strongly recommend using Lumberg style jacks for an easier fit:
