In this episode, we'll DIY our way towards a harsh & metallic sounding double wavefolder. If you want to build along, here's the bill of materials:

1x TL074 quad op amp
2x BC548 transistor
2x BC558 transistor
1x 220k resistor
5x 20k resistor
4x 10k resistor
1x 4k7 resistor
1x 2k resistor
1x 1k resistor
1x 20k potentiometer
1x 10k potentiometer
