1

Fuzz

A form of distortion used for solo lines and riffs, creates a slight 'fuzz' sound on the guitar

2

Overdrive

Created a harder distortion than fuzz, but not as intense as Distortion. Used for riffs

3

Distortion

The most intense form of distortion. Used for power chords.

4

Reverb

An effect added to give an indication of room size. Originally created by recording a sound source in a type of room with the desired amount of reverb (i.e. in a church for lots of reverb)

5

Plate reverb

A method for adding reverb in a studio rather than a specific room. The track is played between two suspended metal plates from a speaker at one end, picked up by a microphone at the other. The sound bounces off the plates, creating a reverb effect.

6

Spring reverb

The same as plate reverb but using springs instead of plates. The sound is played from one end of the springs and is picked up at the other by a microphone. Used in guitar amps.

7

Wah-wah

A effect most commonly used on guitars, using a pedal. Created by having a filter that opens and closes with the movement of the pedal. Sounds like someone saying 'wah wah'

8

Limiter

A compressor with extreme settings (ratio of 15:1+). Used in live performances to protect equipment and ears.

9

What is compression?

A form of dynamic processing used to reduce the dynamic range of a piece.

10

Sample rate

The number of sample taken per second. Measured in Hz.

11

Bit depth

The rate of quantisation. Measured in bits.

12

Nyquist theory

The theory that music must have a sample rate of at least double the highest frequency audible to human ears. This is why sample rate is usually 44.1 kHz / 44100Hz.

13

Chorus

An effect used to give the impression of multiple instruments. The signal is doubled, slightly detuned, then played back with the original signal.

14

Flanger/phaser

The signal is doubled. Delay is added to the doubled signal with varying delay times and played back with the original. This gives a 'wooshing' effect. Heard in the chorus of 'Killer Queen' by Queen.

15

Slap-back echo

Delay with an extremely short delay time and only one repeat. Used on bass parts to imitate 'slapping the bass'.

16

High-pass filter

A filter that cuts frequencies below a certain cut-off point. Sounds like music is playing out of someone else's headphones.

17

Low-pass filter

A filter that cuts frequencies above a certain cut-off point. Sounds like hearing music from inside a club.

18

Band-pass filter

A filter that cuts all frequencies except a specific band of frequencies. Sounds like someone talking on an old-style telephone.

19

Notch filter

A filter that cuts very specific frequencies.

20

Comb filter

Multiple notch filters so it looks like a comb on the EQ.
