Page 2: Important Notes
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. -
Page 3: Channel Order
Yet more important notes specific to this circuit CHANNEL ORDER Our version of this circuit runs left channel (A) into right channel (B). Why? Because that’s how it should be. If you don’t like it you’re welcome to wire up the daughterboard differently, wiring IA and OA to IB and OB, and vice versa. - Page 4 Schematic - Main PCB The two channels are identical. The small circuit shown around IC1 is the charge pump. The connections for the 4-way DIL clipping selector switch are shown above (S1.1 - S1.4). Switches 1 and 2 will connect the two sets of diodes for circuit A, 3 and 4 for circuit B. You can engage one, both or neither set of diodes for each circuit.

See leave out C19-21, D14-15, IC1, later in the document for tips on mounting. and place jumpers as shown below: Positive (anode) legs of the electrolytic caps go to the square pads.

Page 8: Main Pcb Assembly
MAIN PCB ASSEMBLY Nothing too unusual about it. We recommend placing some components on the pot side of the PCB (as shown below) to give better clearance when joining the two PCBs together. It’s best to lay C5, C18, C23 and C24 flat against the board. Use EITHER a pot or trimmer for each PRESENCE control. - Page 9 MOUNTING THE POTS We have a lot of pots on there and they all need to line up nicely, both with the PCB and each other. The best way to do this is a combination of eye and using the enclosure for alignment. Snap the small locator tags off each pot so they can sit right against the enclosure.
- Page 10 ASSEMBLE DAUGHTERBOARD AND jOIN THE PCBS This procedure is the same for both versions of the daughterboard. Solder in your daughterboard resistors, caps and ICs as appropriate. Push your LEDs through their pads (long leg to round pad), and bend the legs slightly so they can’t slide back out. Set the height of your footswitches as desired using the lower nut in each case.
- Page 11 WIRE IT ALL UP You should now have a fully assembled unit, ready for the offboard wiring. Of course, yours will have ICs placed in the sockets now! So let’s get it wired up as shown below. If you don’t want to use a battery just leave those connections out.
