envelope filter

An envelope filter reacts to your playing dynamics, opening and closing its sweep based on how hard you pick. Dig in and it quacks, ease off and it softens — delivering that unmistakable funk snap, auto-wah bounce, and touch-sensitive groove that feels alive under your fingers. It’s expressive, rhythmic, and full of character.

Use it to bring movement to clean riffs, add vocal-like sweeps to bass lines, or inject serious funk into your rhythm playing. From subtle shimmer to full-on 70s squelch, an envelope filter turns your picking hand into the control knob.

Filter

A filter pedal shapes your tone by emphasising or cutting specific frequencies, letting you sculpt everything from subtle tonal shifts to bold, sweeping textures. Unlike traditional wah or envelope effects, filters can be static or controlled in different ways, giving you focused control over how bright, dark, sharp, or resonant your sound becomes.

Use a filter to tighten the low end, tame harsh highs, or create synth-like sweeps and rhythmic movement. Whether you’re refining your core tone or pushing into experimental territory, a filter pedal gives you precise control over the flavour of your sound.

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.

Preamp

A preamp pedal shapes and boosts your guitar’s signal before it reaches your amp or recording interface, giving you control over tone, gain, and headroom. It acts as the first stage of amplification, adding warmth, clarity, and character while preparing your signal for the next part of the chain. Some preamps emulate the response of classic valve circuits, while others offer clean, transparent tone shaping ideal for acoustic instruments or direct recording setups.

Used on its own, a preamp pedal can serve as the foundation of your tone, providing a consistent core sound wherever you play. When combined with other effects, it enhances dynamics and helps each pedal sound more defined and natural. Whether you’re looking to push your amp harder, bring life to a dull signal, or refine your sound for the studio, a good preamp pedal adds presence, punch, and musicality to any rig.
