The Keeley Halo Stereo Dual Echo is a delay pedal from Keeley that packs a true stereo path into a compact enclosure. It is a dual-echo design delivering up to 1500ms per channel, built on a DREAM multi-core DSP for sound quality, and it carries guitarist Andy Timmons' signature: one of its presets recreates his modulated dual-echo sound, with the notes held together by tape-style effects like modulation, saturation and compression1.
Controls, presets and footswitches
The Rhythm Mode selector delivers 5 delay types, including Andy's unique "Halo" sound1. Beyond the delay types, the pedal includes presets, tap tempo, delay rhythms, optional modulation and a high degree of tweakability1.
The preset system allows easy switching between two presets, assigning them to each footswitch1. The soft stomp switches handle tap tempo, infinite hold, preset save/recall, and more1.
The repeats' character can be radically manipulated through alternative controls for saturation, tone, and shelving filters, which are accessible by pressing and holding the Feedback knob1.
| Control or switch | What it does |
|---|---|
| Rhythm Mode selector | Selects among 5 delay types, including the "Halo" sound1 |
| Feedback knob (press and hold) | Opens alternative controls for saturation, tone and shelving filters1 |
| Two footswitches | Tap tempo, infinite hold, preset save/recall and more1 |
| Preset system | Two presets, assignable to each footswitch1 |
| Bypass option | True-Bypass or Trails1 |
Related Keeley delays
The Keeley Halo Andy Timmons Dual Echo sits alongside other delays in the Keeley range, including the Eccos and the Multi Echo ME-8. On the Halo Stereo Dual Echo itself, pressing and holding the Feedback knob opens a set of alternative controls for saturation, tone, and shelving filters; as Keeley's Simon Keats put it, "The repeats' character can be radically manipulated through the alternative controls for saturation, tone, and shelving"1.
The hidden controls behind the Feedback knob are easy to miss: they are not labeled on the face of the pedal, and they change how the repeats sit in a mix, from saturation and tone to shelving filtering1.

Questions
Is the Keeley Halo a digital or analog delay?
The Halo is a digital delay. It runs on a DREAM multi-core DSP platform, which Delicious Audio describes as delivering stunning sound quality. That digital engine is what allows the pedal to fit a true stereo path, five delay types, presets, tap tempo and optional modulation into a compact enclosure, while the repeats themselves are shaped with tape-style effects like modulation, saturation and compression.
How long can the Halo delay?
The Halo delivers up to 1500ms of delay time per channel. Because it is a dual echo with a true stereo path, each side of the signal can carry its own delay line, which is the basis of the modulated dual-echo sound associated with Andy Timmons' signature preset.
Does the Keeley Halo have tap tempo?
Yes. The Halo's soft stomp switches handle tap tempo, along with infinite hold, preset save and recall, and other functions. The pedal also offers delay rhythms and optional modulation, with a high degree of tweakability according to Delicious Audio's product page.
Is the Keeley Halo true stereo?
Yes. Delicious Audio describes the Halo as packing a true stereo path into a compact enclosure, and it is a dual-echo design delivering up to 1500ms per channel. The pedal can also be set for True-Bypass or Trails operation.
Is the Halo available in true bypass?
Yes. The Halo offers a choice between True-Bypass or Trails, so players can decide whether the delay repeats continue to ring out after the pedal is switched off or the signal path is fully bypassed.
Where is the Keeley Halo made?
The Halo is made in the USA by Keeley Electronics.
