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. Connect

IN and OUT to the jacks as shown. Connect all the GNDs together (twist them up and add a small

amount of solder to tack it). Connect the b lead to the 9V wire, same method. Plug in. Go!
You’ll have to connect the wire from pad O2 to either O1 or O3, or you’ll get no signal from the

Distortion section.
There’s no need to connect power to the OV and OG pads - these are purely to supply power to an

LED if you’re adding the Octave footswitch.
If you have a circuit tester (we sell a few!) just use that as normal.
