A pedal is a compact device that guitarists use to alter their instrument’s sound by shaping effects such as distortion, delay, reverb, and modulation. Typically housed in a rugged enclosure and controlled by footswitches, pedals are designed to be placed on the floor for hands-free operation during playing. They can be analogue or digital, true bypass or buffered, and come in countless varieties to suit different styles and preferences. Pedals are essential tools for creating signature tones and adding colour and texture to a guitarist’s sound.
A guitar phaser is an electronic effect used to alter the sound of a guitar by creating a series of peaks and troughs in the frequency spectrum of the audio signal. This effect is achieved through a process called phase shifting, where the audio signal is split into two paths. One path remains unchanged, while the other is subjected to an all-pass filter that shifts its phase. When these two signals are recombined, they interfere with each other, creating the characteristic swooshing or swirling sound associated with phasers. This effect can add a sense of movement and depth to the guitar’s tone, making it a popular choice for both rhythm and lead playing.
Vibrato is a musical effect that adds depth and expression by subtly varying the pitch of a note. In guitar playing, this can be achieved by bending the string back and forth, using a vibrato bar (whammy bar), or with a dedicated vibrato pedal. Unlike tremolo, which modulates volume, vibrato modulates pitch—creating a shimmering, vocal-like quality that brings notes to life. Whether used gently for soulful bends or more dramatically for psychedelic textures, vibrato is a powerful tool that adds emotion, movement, and personality to your sound.
