you’re having trouble reading the color bands, there are
apps that make easy working of identifying them. Or, try
using a multimeter to read a resistor’s value. Just set your
multimeter to ohms and connect the test leads on each
side of the resistor.
A number of dierent components are used to make an
eects pedal. Here’s an overview of what they do..
RESISTORS
A resistor is used in an electrical circuit to present an
opposition to current ow. It resists the amount of
current that can pass through it.
A resistor’s value—the amount of resistance it creates—
is rated in ohms (). The higher the ohmic value, the
greater the resistance to this ow of current. For
example, a 100 resistor creates ten times as much
resistance as a 10 resistor.
Resistor values are indicated by colored bands, read from
left to right. The rst color in the code is usually the one
painted closest to a lead. When a gold or silver band is
present, it’s always one of the last colors in the code. If
