To build the stock circuit with no modifications...

    Install jumpers to bridge the breaks at Pads C and D (below and to the left of IC2).

    Install a jumper in place of C24 (below the Speed pot).

    C29 appears twice in the layout (to the left of IC6 - 4047). Do not install the one that connects to Pad F.

    Install a jumper to bridge the gap at Pads K (to the left of the Enhance pot).

    The values of R41 and R42 can be decreased to make the output volume louder. A value of 33K for both should give close to unity output. A value of 27K for both will give a slight boost and should allow a volume control to be added at the output if desired. Try a 10K audio taper pot with lug 3 tied to the circuit output, lug 1 to ground and take the new output from the wiper (lug 2).

For the stock build use a MN3007 chip for IC10...

    The entire circuit runs on regulated +15VDC.
    Use a +15V regulator (LM7815) for IC7.
    Use a 18VDC wall wart power supply to power the pedal.

    Do not install C38 (0.1uF) located below C33.

    Do not install Q2. Install a jumper between the outside pads for Q2. Ensure that no contact is made with the center pad.

    Install jumpers from P to P1... R to R1... T to T1.

    Install R70 (1K) and R71 (14K) as shown.
