IT is actually possible to build a very simple pedal yourself. You can tape two tinfoil &quot;electrodes&quot; on cardboard and fold it so that they touch when it&#x27;s completely folded. Then also put some sponge between the folded cardboard so that it releases reliably. If you connect a mono audio cable to the electrodes you have a working pedal. This worked in a pinch for an electronic drum set and it is also much quieter than a real pedal.
