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.

Two of the power and signal pads on the PCB You should solder all other board-mounted conform to the FuzzDog Direct Connection components before you solder the pots. Once format, so can be paired with the appropriate they’re in place you’ll have no access to much of daughterboard for quick and easy offboard the board.
Initial wiring USE WIRES! Our ribbon cables are unlikely to be of any use unless you’ve compromised your enclosure layout to line up the pads to daughterboards. If you aren’t going to use a footswitch to engage/bypass the OCTAVE section of the circuit, add a jumper as shown below.

Testing You can test the Distortion and Boost sections individually, as if they’re separate boards. Do the test wiring as shown below for each section. UNDER NO CIRCUMSTANCES will troubleshooting help be offered if you have skipped this stage. No exceptions. Solder some nice, long lengths of wire to the board connections for 9V, GND, IN and OUT.

Wire it all up The image below assumes you’re using an Octave Bypass footswitch. If not just leave that out, having added the jumper shown earlier in this document. You should also connect OV and OG to V and G on the Octave daughterboard, we just left them out of the image as it would get messy.

Keeping up appearances... On the bigger box versions of this kit, the LEDs all sit to the same side of the footswitches. However, that would look decidedly weird on the two switch, 1590BB version. To keep things sweet you’ll have to flip the Distortion side daughterboard over before soldering in the footswitch and LED.

On/Offboard wiring We designed the board to fit nicely in a 1590BB with all controls mounted on the PCB. Using a bigger enclosure means some pots need to be wired offboard. The images on the next two pages show which pots need to be wired. You may need to bend the legs down to ensure they don’t touch the PCB in some places.
If you’re using a different type you’ll have to work out for yourself how far down the pots need to be to allow clearance for any lugs. On the 1590DD enclosures there’s an extra rib in the centre, so take that into consideration when drilling your middle footswitch and your DC socket hole. FuzzDog.co.uk...
