Not so long ago a friend showed me a little circuit which I thought was quite interesting (The Wah Pedal), a simple variable active filter with a couple of transistors but with no variable reactive components. So I thought eventually, some day, I should take the time to understand it more deeply, simulate it and put it in a little PCB; a great example project for learning a couple of new design tools. Well I did!
