PCB SCHEMATIC
MODIFICATIONS
Replacing the diodes allows you to explore a range of distortion tones: germanium diodes (1N60, 1N270, or 1N34A) produce a softer, smoother distortion. Silicon diodes (1N914 or 1N4148) deliver a harder, more aggressive tone. LEDs create a fuzzier, crunchier sound. You can also experiment with different combinations, either symmetric or asymmetric clipping.
GENERAL DESCRIPTION OF COMPONENTS
Resistors
Resistors don't have polarity, so you can place them in any direction. Determine their resistance value by using a multimeter or by reading the color bands.
Electrolytic capacitors
Electrolytic capacitors have their value and maximum voltage rating printed on the body. The negative pin is indicated by a white stripe along the can, and it also has a shorter leg. The longer leg is positive. Never exceed the maximum voltage rating. Ensure the capacitor's voltage rating is at least double that of your power supply (e.g., use an 18V capacitor for a 9V power supply).
Polyester capacitors
Polyester capacitors don't have polarity and can be placed in any direction. Their value is marked using a three-number code. The first two numbers represent the first and second digits of the value, and the third number is the multiplier code (read in picofarads, pF).
Ceramic capacitors
Ceramic capacitors don't have polarity and can be placed in any direction. Their value is marked using a three-number code. The first two numbers represent the first and second digits of the value, and the third number is the multiplier code (read in picofarads, pF).
Diodes
Diodes have their model number printed on them. The polarity (cathode) is indicated by a stripe or ring near one end. This ring corresponds to the polarity marking on the PCB.
Led diodes
LEDs (Light Emitting Diodes) have polarity. The cathode is indicated by a flat edge on the side of the LED's plastic casing and a shorter leg. The longer leg is the anode. On the PCB, the cathode is marked with a flat side and the anode with a round side.
Transistors
Transistors are three-terminal components with their model number printed on them. To ensure correct orientation, one side of the transistor's body is flat while the other is curved.
Potentiometers
Potentiometers have their resistance value marked on them. They are also marked with a letter to indicate their taper: A for logarithmic, B for linear, and C for reverse logarithmic.
