Lava Rim 2
Another request. Aron Nelson’s Lava Rim 2. I have no clue why the input level control pot is called “Bias”. That’s the reason why i used quote marks around it…

Fortunately MarkGor on Freestompboxes traced his pedal and also removed some of the components so they could be measured to check the values, … Read more
