  • Page 4: General Guideline For Components

    General guideline for components You can use this guideline if components on the previous page are not marked as a specific type.  Capacitors: All values under 1nF should be ceramic disks. From 1nF up to 1uF should be SMF/MKT (foil/metal film capacitors) and over 1uF use electrolyte caps (or tantalum) 16V+ rated and watch out for polarity! ...

    Notice that in the “off” position the effect input is connected to ground to prevent possible oscillation. The LED requires a resistor (R led in the diagram) depending on the type of LED you are using. An ultra-bright red or blue LED requires a 3k3 resistor, Green requires 680R.
