Resistors & Diodes
BREADBOARD FLOW
Power rails flow horizontally.
The negative rail will connect to the pin
header marked GND, and the positive rail
will connect to the pin header marked VCC.
Audio rails flow vertically.
Channels a-e are connected, and channels
f-j are connected.
READING RESISTORS
Reading resistors may seem intimidating, but it’s a very important aspect of
breadboarding and is actually very easy!
To determine the resistor value, follow the table and colors below. To ensure
you are reading the correct value,
keep in mind that the tolerance band is always found on the far right.
Shown below are the resistors and values that we’ll be using in this build.
STEP ONE | POWER FILTERING
Power filtering helps to filter unwanted noise from power supplies, while
preventing incorrect polarity
from damaging the circuit. Ensure that polarized components (diode +
electrolytic capacitor) are
inserted correctly. In the schematic below, the power shows 9V, whereas the
breadboard shows VCC.
Please note that for the majority of pedal circuits, these terms are
interchangeable.
STEP TWO | INPUT
The input capacitor blocks AC signal, while setting the amount of low
frequency audio allowed into the
circuit. The pull down resistor prevents popping from the switch.
STEP THREE |GAIN STAGE
Signal enters the transistor and is amplified, based on the value of the bias
resistors 33K and
4.7K. The 1K and 47u establish the gain amount.
STEP FOUR | OUTPUT
The volume knob acts as an attenuator, setting the output volume of the circuit.
TROUBLESHOOTING
Not getting power to the Power Rails/LED is not turning on when the toggle
switch is set to the ‘Engage’ position.
Check that the proper connections are being made from the “VCC” & “GND” pin
headers to the Power Rails. Pay attention to the orientation of Polarized
components (Diodes and Electrolytic Capacitors).
Check the polarity of your power supply. Breadboards require “Center negative”
polarity (as is with the power supply shipped with the bundle).
Not getting any effect when the toggle switch is set to the Engage position.
Most common issues will pertain to the proper connections being made. This
could be as simple as a component being 1 slot away from the correct Audio
Rail.
Check that transistor are in the correct orientation, and not flipped around
180 degrees.
Getting effect when toggle switch is set to Engage, but it doesn’t sound as
expected.
Check that the transistor is in the correct orientation and not flipped around
180 degrees. Check that the resistors are in the correct place and didn’t get
swapped with a different value. Pay
attention to the orientation of Polarized components (Diodescand Electrolytic
Capacitors).
