Designed and manufactured in Oklahoma, USA.

The Keeley Electronics NOCTURNE Andy Timmons Reverb captures the haunting beauty and tonal atmosphere of Andy Timmons’ signature sound — the spacious half of his HALO tone. Known for its lush ambience and emotional depth, Andy’s reverb has now been carefully isolated and perfected as a standalone effect.

Designed to Inspire

Developed in collaboration with Andy Timmons, the NOCTURNE brings players the same immersive reverberation that defined his HALO Dual Echo and HALO Core pedals. From subtle ambience to cinematic space, the NOCTURNE allows players to create that same expressive, touch-sensitive bloom that trails effortlessly behind every note.

Three Powerful Modes

Choose from three reverb modes — Nocturne, Spring, and Plate — each designed to capture a distinct personality. The simple four-knob layout of Tone, Level, Decay, and Modulation makes it easy to shape anything from vintage echo-chamber warmth to a shimmering, modern wash. The Preset Switch lets you store your favorite settings for instant recall, while the optional Trails mode ensures your reverb fades naturally even when bypassed.

Unrivaled Flexibility

The NOCTURNE offers a flexible signal path with True or Buffered Bypass, Expression Pedal control, and MIDI compatibility for up to 72 presets. Whether you’re running mono or stereo, wet/dry, or full wet for parallel rigs, the NOCTURNE adapts easily to any setup. Built on Keeley’s award-winning Core architecture, every component and line of code is tuned to make this reverb feel musical and alive.

Like every Keeley pedal, the NOCTURNE Andy Timmons Reverb is designed and hand-built in Oklahoma, USA, engineered for the working musician, and voiced for inspiration.

The Nocturne “sound” is essentially the beauty of what we all love

about the Halo sound, but without the cross talk of repeats of the delays.

It’s reverb achieved (created) from a completely different angle.

“What If?” “Could We?” It’s the sound I’ve been hearing, but was unable

to get with other reverbs. It’s the most inspiring reverb I’ve ever heard and

I just want to play all day basking in its beauty.
