After doing a layout for the Nordland Overdrive, I thought I would compare the differences to the designers original Nobels version. Apart from some insane power filtering / protection and LED circuitry, there's a couple of small changes.
Traced schematic for the Nordland is here, on Aion FX
- Hard clipping diodes to ground, instead of to bias voltage
- Resistor to ground instead for bias voltage
- Some coupling capacitor value changes
- I omitted a few small details, like 10 ohm resistors providing some additional separation between components
- 50k tone pot instead of 20k
