Place jumper wire across pads J1-J2
This configuration will give you 18V
at the V pad on the connection strip.
Your on-board LED will still get 9V.
This configuration will give you -9V
at the V pad on the connection strip.
Use this to supply your positive-
ground effects. Connect the V pad
from the daughterboard to the -9V
connection on your circuit, and
connect Ground as normal. Your on-
board LED will still get 9V.
You can wire up your jacks as
normal and daisychain the effect on
your normal negative-ground supply.
Extra GND pads have been included for wiring convenience.
*Use a 7660 chip with a suffix begining with ‘S’, otherwise you’ll likely hear a high
pitched whine from your circuit.
The power and signal pads on the PCB conform to the FuzzDog Direct Connection format.
Be very careful when soldering the diodes. They’re very sensitive to heat. You should use some kind
of heat sink (crocodile clip or reverse action tweezers) on each leg as you solder them. Keep
exposure to heat to a minimum (under 2 seconds). You should really use a socket for the IC. If not,
be extra careful not to overheat.
Negative (cathode) legs of the diodes go to the square pads. That’s the short one on the LED.
Labels on the top side of the PCB are:
V-IN - your positive connection from your DC socket
JI - Jack IN
CI - Circuit IN
V - Circuit Voltage Supply
CO - Circuit OUT
JO - Jack OUT
