All the switches are good, the other side of the DPDT is for the LED
When I jumpered the octave switch, that was because I removed all the stomp switch wiring while I was tracing the circuit, those wires break off really easy, just look at them wrong and they fall off. I knew that from another Joyo I have. So with no octave switch connected, I jumpered the connection on the PCB to make the octave turn on. All you need to do to make the pedal work correctly is what is shown in that picture, nothing else.
>Is it still nice and thick and chunky?
There is still plenty of distortion, sustain and grunge that's for sure, maybe more. To me it sounds a lot lot better. Probably the same basic sound but easier to hear the grunge and distortion. Like if you had a blanket over your speaker box and then took it off. Difficult to explain.
Turning the two 10uF electrolytic caps around will make the octave effect work. Swapping the other 2 caps was not such a dramatic change.
Be careful with the PCB, it is not real strong and is not built strong enough to handle more than 1 or 2 component replacements IME.
