Adding Passive Tone Control to a Booster Pedal

In this video I go through some simple passive tone control options for boosters I did previously.
I try out 4 different passive tone controls - a simple filter (found in ProCo Rat pedal), DIY favourite Big Muff style tone control, and then VOX and Marshall style tone stacks that have more than one knob control.
