A delay pedal records your signal and plays it back after a set time, creating echoes that can range from tight, slapback repeats to long, atmospheric trails. It’s one of the most versatile effects, used to thicken tones, add rhythmic depth, or build spacious, ambient layers. Analogue delays offer warm, decaying repeats that blend naturally with your tone, while digital units provide pristine echoes with precise control over time, feedback, and mix levels.
From classic rockabilly and tape-style echoes to modern looping and shimmer effects, delay pedals have become essential tools for shaping sound. They can make solos soar, rhythms pulse, or transform simple chord progressions into cinematic textures. Whether used subtly to add dimension or boldly to create soundscapes, a good delay pedal can completely redefine the feel and atmosphere of your music.
Expression pedals allow real-time control over specific parameters on compatible guitar pedals, such as volume, delay time, modulation depth, or filter sweep. Used with an expression input, they let players shape effects dynamically with their foot, adding movement and performance control that cannot be achieved with fixed knob settings.
Your pedal is like a signature dish for your sound — a flavour-packed creation that transforms the bland ingredients of your guitar into something unforgettable. Each one adds its own seasoning, texture, and heat, turning a simple meal into a feast of tone.
These tasty little boxes sit in a row, like plates on a buffet, letting you mix and match flavours as you play. With one tap of your foot, you can swap sweet for spicy, subtle for smoky, and serve up something completely new. From the comfort food of warm overdrive to the fiery kick of fuzz, from smooth jazz sauce to heavy-metal spice, pedals give players a full menu of options to express their taste. And just like with food, once you’ve tried one dish, you’ll want to sample them all.
Collecting, trading, and discovering new flavours soon becomes part of the joy of being a tone-loving gourmet geek with a guitar.
A looper pedal records and plays back sections of your playing, allowing you to layer sounds and build full arrangements on your own. By capturing short or long phrases, you can create rhythm parts, harmonies, or entire backing tracks in real time. Most loopers offer basic controls for record, overdub, and playback, while advanced models include multiple tracks, tempo syncing, and memory storage for saving your loops.
Loopers are invaluable for practice, songwriting, and live performance. They help you explore ideas, refine timing, and experiment with textures — from solo acoustic performances to complex ambient soundscapes. A good looper pedal becomes an instrument in itself, letting you improvise, arrange, and perform with creativity and freedom, turning one guitar into an entire band.
MIDI pedals use the Musical Instrument Digital Interface standard to communicate with other guitar pedals, effects units, and hardware. They allow control over presets, parameters, and switching across multiple devices from a single controller. MIDI integration makes it possible to build complex, synchronised pedal setups while keeping control simple and consistent.

Pitch pedals alter the frequency of your guitar signal, changing the perceived note or adding harmony. They can shift notes up or down by fixed intervals, create harmonies, or produce dive-bomb and whammy-style effects without a tremolo arm. Pitch shifters and harmonisers are great for thickening solos, simulating multiple guitars, or experimenting with creative, otherworldly sounds that expand your tonal range.
A reverb pedal is like the rich sauce that ties every flavour on the plate into one smooth experience. It adds depth, warmth, and atmosphere — the sonic equivalent of a perfectly reduced glaze that lingers on the tongue. Whether you’re after the subtle ambience of a cosy café (spring or plate reverb) or the grand echoes of a cathedral (hall or shimmer reverb), this is where your tone breathes and expands. A touch of reverb can turn a dry sound into something lush and inviting — but pour on too much, and it’s all you can taste. Used with finesse, it’s the finishing touch that transforms your tone from plain to unforgettable.
