The Sound of Andy Timmons’ HALO

For years, Andy Timmons kept his mysterious HALO effect a secret: a dual echo sound blending modulation, compression, and tape-style saturation to create lush rhythmic delays that dance like reverb diffusion. Now, with the Keeley HALO Core, those same textures are accessible to every player.

Notes bloom, shimmer, and intertwine rhythmically, perfect for ambient swells, soaring leads, or rhythmic textures that add dimension to any mix.

Why Choose the HALO Core?

The HALO Core offers studio-grade sound quality in a grab-and-go pedal that’s simple enough for beginners yet powerful enough for professionals. With intuitive controls, stereo operation, and Keeley’s signature craftsmanship, this pedal is built to inspire.

“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!”
