Chorus

A chorus pedal thickens and widens your tone by subtly duplicating your signal and shifting it slightly out of tune and time. The result is movement — shimmering cleans, liquid arpeggios, and that unmistakable 80s swirl that makes single notes feel fuller and chords sound expansive. From gentle sparkle to deep, watery modulation, chorus adds dimension without overwhelming your core sound.

Use it to bring life to clean passages, soften driven tones, or create spacious textures that sit beautifully in a band mix. Whether you’re after subtle depth or bold, warbling character, a chorus pedal is a simple way to make your guitar sound bigger, richer, and more immersive.

Flanger

A flanger is a type of guitar effects pedal used to create a swirling, whooshing sound by modulating the phase of an audio signal. It works by combining the original signal with a slightly delayed and modulated version of itself. As the two signals interact, they create peaks and troughs in the frequency spectrum, resulting in the characteristic “jet plane” or “swooshing” sound associated with flanging.

Key features of a flanger pedal include:

1. **Rate**: Controls the speed at which the delayed signal is modulated. Higher rates produce faster modulation, while lower rates create slower, more subtle effects.

2. **Depth**: Adjusts the intensity of the modulation effect. Higher depth settings result in more pronounced sweeps, while lower settings produce a gentler effect.

3. **Manual (or Range)**: Sets the center frequency of the modulation. This control allows you to focus the effect on specific frequency ranges, altering the tonal character of the flanging.

4. **Feedback (or Regeneration)**: Determines the amount of modulated signal that is fed back into the effect. Increasing feedback can create more pronounced peaks and troughs, resulting in a more intense effect.

Flanger pedals are commonly used in various music genres, including rock, metal, and psychedelic music, to add movement, depth, and texture to guitar tones. They can be used subtly to add a touch of modulation and dimension to a guitar sound, or more prominently to create dramatic swirling effects. Overall, flanger pedals offer guitarists a versatile tool for shaping and enhancing their tone, adding a dynamic and expressive element to their playing.

Guitar Effects Pedals

Guitar Pedals

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.

Tremolo

A tremolo pedal modulates the volume of your guitar signal up and down in a rhythmic pattern, creating a pulsing or wavering effect that can sound vintage and hypnotic or sharp and choppy depending on the settings. It’s one of the oldest effects in guitar history, famously used on classic amps from the 1950s and ’60s.

Most tremolo pedals let you control the speed, depth, and wave shape, allowing you to go from smooth, subtle swells to intense stuttering tones. It’s a simple but expressive effect that adds movement and character to your sound.

Vibrato

Vibrato refers to a guitar pedal effect that modulates pitch slightly up and down, creating movement and a sense of wobble in the sound. Unlike tremolo, which changes volume, vibrato affects pitch only, producing anything from subtle shimmer to pronounced, warbling textures. It is often used to add character, depth, and vintage-style modulation to guitar tones.
