Important notes

If you’re using any of our footswitch daughterboards,

DOWNLOAD THE DAUGHTERBOARD DOCUMENT

Download and read the appropriate build document for the daughterboard

as well as this one BEFORE you start.

DO NOT solder the supplied Current Limiting Resistor (CLR) to the main

circuit board even if there is a place for it. This should be soldered to the

footswitch daughterboard.

POWER SUPPLY

Unless otherwise stated in this document this circuit is designed to be

powered with 9V DC.

COMPONENT SPECS

Unless otherwise stated in this document:

Resistors should be 0.25W. You can use those with higher ratings but

check the physical size of them.

Electrolytics caps should be at least 25V for 9V circuits, 35V for 18V

circuits. Again, check physical size if using higher ratings.

LAYOUT CONVENTIONS

Unless otherwise stated in this document, the following are used:

Electrolytic capacitors:

Long leg (anode) to square pad.

Diodes:

Striped leg (cathode) to square pad.

ICs:

Square pad indicates pin 1.
