How to choose guitar effects
TIPS FOR BEGINNERS:The most popular and widely-used effects are ‘distortion’ boxes. These effects distort electric guitars to produce the quintessential hard rock and heavy metal sound. An undistorted electric guitar essentially sounds similar to an acoustic guitar.

The basic categories of guitar effects:
Overdrive effects simulates the ‘overdriving’ of a tube amp, with the resulting sound of the electric guitar being characteristically ‘cracked’ and ‘gritty’. Overdrive took hold in music during the 1960s.
Distortion is even more aggressive than overdrive, has a longer reverb and can be reliably found in all metal genres.
You definitely know equalisers from HiFi players and the like. They serve to amplify or reduce certain frequencies such as bass, midrange and treble. These effects strengthen/weaken the frequency in the given range of roughly o +- 12 to 20 decibels.
Phaser effects change the volume in the chosen frequency band while also adding to the original signal its phase shifted copy. In practice, it seems as if the phaser is breathing.
Tremolo is one of the oldest effects, and thanks to its simple technical realisation, it is often built into amps such as Vox and Fender. The effect regularly repeats the attenuation and re-strengthening of the signal, the speed of which can be adjusted. When set properly, a nice, swinging and pulsating effect is achieved without changing the resulting character or height of the sound.
Modulation effects such as chorus, digital echo and especially reverb began to appear in the mid-1970s. Reverb is one of the most frequently used effects, and many guitars are in fact sold with this feature built-in. Depending on the setting, the effect delivers an echo sound ranging from a small room up to a large hall.
Chorus attempts to imitate the unison of multiple instruments playing simultaneously by dividing the signal and adding others to the original (lightly modified). Above all, when used on a pure (undistorted) guitar, the chorus adds volume and richness to the sound. Although chorus sounds best when connected in stereo, the result with a mono connection is also very good.
One of the first delays appeared in the 1950s, and the famous Delay Memory Man was introduced by EHX in the 1970s. In principle, delay generates an echo that returns and repeats depending on the setting. The repeated sound is a precise copy of the original that you play, and the volume of the echo weakens with each repetition.
The wah-wah effect is named after the sound mimicking the human voice that is produced by stepping on the pedal that is typically included.
This type of effect is very popular, especially with solo players on either acoustic or electric guitars. The looper enables the guitarist to record short passages and play them back in a repeating loop. You can then play a melody, sing, etc., in these loops.
