Decide before building the effect which mods or options you want to try so that you do not need to desolder parts later.
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! ...
Modifications The original does not use a 2k trim pot VR1. If you do not want to use the bias trim pot then you can solder a 1k resistor holes marked with A and B, and also use a 1k between C and D. ...
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.
