How to convert your DS-1 to Keeley All seeing eye and ultra mods

Step 3 Putting in the new components

• Place a 2.4k resistor in R13
• Place a 20k resistor in R39
• Place a 1.5k resistor in R14
• C1, C3, C5, C12, C13 all need to be installed with 0.1Uf Caps
• C2, C8, C9, C14 need to have 1uF caps installed (on the referance diagram I used two 0.47uF caps soldered together)
• C11 needs to have a 0.047uF cap
• C7 needs to be changed to a 220pf cap

See below diagram for how they sould look in place

• Solder a 47pf cap across clipping diodes, you will need to look at the below image to see where to solder it.

Instead of soldering the 47pf cap on the bottom of the board, it can be wired in parallel with D4 or D5. The 47pf cap I got was too big for the bottom of the board so I put the capacitor in the holes for D5 and soldered the led to the leads of the capacitor.

I opted to NOT install the 47pf cap as indicated in the last step here. The pedal still sounded great in both modes.

have you attached that 47pf cap in the picture of the circuit board, or haven't you. That piece of wire can't be the cap can it?
