Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement.

The Keeley Halo is Andy Timmons' signature dual echo, recreating the long-secret modulated delay that has shaped his lead tone for decades. It produces a cascading, dancing series of stereo repeats held together with tape-style modulation, saturation, and compression, creating a lush, reverb-like diffusion that stays out of the way of the dry guitar. The signature sound comes from modulated delays subtly drifting in time across the stereo field while leaving the initial note uneffected. Two independent sides, A and B, switchable on the fly, give players two delays in one, covering slapback, stereo chorus, saturated tape echo, and clean digital repeats. A memory bank stores up to eight presets for instant recall.
The Universal Audio UAFX Orion is a premium tape echo pedal recreating the warm, organic sound of classic vintage tape delays like the Echoplex, using UA's acclaimed high-end DSP and modeling. It captures authentic tape saturation, wow and flutter, and self-oscillation, plus stereo operation and app control, favored by players wanting genuinely vintage tape-echo character with modern reliability.
