[capacitors]

Capacitors, again available in a wide range of values, can be wired between the pairs of points. These may change the tone of the effect produced or pulse the sound in differing ways.



NOTE: Some larger electrolytic capacitors can hold a substantial charge and can transfer it to you in the form of a very real shock.These are cylindrical, two-lead (usually) devices, the ones of concern most often being larger than a cigarette filter. These capacitors appear in the circuitry of strobe lights, power supplies and other higher-voltage dependent applications. They practically NEVER appear in the circuits here under discussion. However, all beginner's guides to electronic circuit design cover this subject. If you're not familiar with how the electrolytic capacitor looks, get a guidebook, (again, like the one by Forrest Mims Jr. at Radio Shack), and learn these basics. Such capacitors are easy to recognize and discharge, in the very rare event that you should ever find one in the way.
