Keeley Halo Core Reverb & Delay Pedal

The Keeley HALO Core delivers Andy Timmons’ legendary dual-echo sound in a streamlined, easy-to-use pedal format. Built on Keeley’s next-generation DSP platform, HALO Core captures the warm modulation, rhythmic diffusion, and tape-style texture that made the original HALO one of the most celebrated delay pedals ever released.

With three musically powerful modes—HALO, Quarter Note, and Dotted Eighth—this compact version gives players Andy’s iconic ambient dual-delay feel plus more traditional rhythmic delays, all with pristine stereo sound and pedalboard-friendly simplicity.

Andy Timmons’ Iconic HALO Sound — Refined

Andy spent decades refining the mysterious “HALO” dual-echo texture:

• Notes swirl and dance rhythmically

• Modulation and saturation add tape-like warmth

• Compression glues the echoes together

• Ambient diffusion creates a reverb-like smear

HALO Core captures these elements perfectly, giving players a lush, dimensional delay that elevates solos, cleans, and ambient soundscapes.
