Delay

A delay pedal is used to create an echo effect by repeating the original sound after a short time. It works by capturing the input signal and then replaying it with adjustable delay time and feedback. The longer the delay time and the more feedback, the more pronounced the repeating echo becomes, adding depth and space to the sound.

There are different types of delay pedals, including analogue, digital, and tape delay. Analog delay provides a warmer, more natural echo, while digital delay offers clear, precise repeats and additional features like tap tempo. Tape delay mimics the sound of vintage tape machines, adding a distinctive, slightly warbled effect. Delay pedals are widely used across genres to create atmosphere, enhance solos, or add complexity to rhythms.

Just Pedals is a new Guitar Effect Pedals Marketplace – We feature new and used Guitar Effect pedals from different sellers, to purchase online from the UK.

Reverb

Reverb simulates the natural echoes and reflections of sound in different spaces, adding depth and atmosphere to a guitar’s tone. It can range from short, subtle room reverbs to large, ambient cathedral-like spaces. Common types of reverb include spring reverb (found in vintage amplifiers), plate reverb (a smooth studio-style effect), and shimmer reverb (which adds ethereal, harmonised overtones). Reverb is essential in many genres, from surf rock and blues to shoegaze and ambient music. Popular reverb pedals include the Boss RV-6, Electro-Harmonix Holy Grail, and Strymon BigSky, offering everything from classic warmth to expansive soundscapes.
