Keeley Electronics New HALO Core Andy Timmons Effect Pedal
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.
Discover the latest from Keeley Electronics: the HALO Core, a streamlined version of our top-selling HALO Andy Timmons Dual Echo. The HALO Core has three modes: Andy’s iconic ‘HALO’ sound, Quarter Note, and now Dotted Eighth.

Musings from Andy Timmons:
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! – Andy Timmons
A song from Robert Keeley:
“Yesterday… My Halo’s Tap Tempo seemed so far away. Now it looks as if HALO Core’s here to stay. I believe you’ll love the intricate modulation sway.”
