Echo fit for a wizard

Andy Timmons’ mysterious sounding “Halo” effect is a modulated dual echo sound that has long been kept a secret by the tone wizard himself. Andy spent decades combining and crafting the sounds you can now get from the HALO Core. Notes dance rhythmically, almost creating a reverb diffusion. Those notes are held together with tape-style effects like modulation, saturation and compression. The results are stunning.

Here’s what Andy Timmons says:

“I’m thrilled that the Halo Core has “struck a chord” with so many folks! This new version has a third mode with the “dotted eighth” setting which for me is the ultimate division for creating great sounding tap tempo textures. Robert Keeley and his incredible team continually strive to make better and better quality pedals and this Halo Core is the best sounding Halo yet!”

Delay

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.

Reverb

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.
