A guitar effects pedal can be connected between your amplifier and the electric guitar. The pedal's purpose is to give you a sound effect that can be switched between the amp and your guitar. It's probably worth clarifying the terminology first. Although some pedals move forwards or backward like volume pedals or wah-wah pedals, most effects pedals can be used as on/off devices.
They have a simple footswitch to engage or bypass the effect. You can use pedals in subtle ways, particularly when they are used together to create endless sounds. You can also check out more about guitar effects pedals from the link https://mochaearth.com.au/collections/guitar-pedals.

Overdrive and distortion are the most common types of pedals. This is the sound that rock produces, and most amplifiers have it built-in. Sometimes, the amp's distortion can be quite minimal, especially for less expensive amps. Older amplifiers don't distort much unless they are turned up to concert volume. This is why the pedal exists. Overdrive and distortion are two different types of the same thing. The former is generally lighter and more severe than the latter.
There are many other types of guitar effects pedals. Multi-effects boxes are a popular choice for beginners. They contain decent approximations to all the most common effects and can be used wherever you want.
However, guitar pedal effects are not all that you need to know. Music theory and harmony are also important. It might be useful to learn about chords for the piano, as it is easier to learn harmony using the piano than the guitar. You should also learn new skills. Every guitar student should know how to change the strings on an acoustic and electric guitar.
