ADG is happy to announce the return of Keeley’s collaboration with Andy Timmons. NOCTURNE is a brand-new reverb space based on their previous work on the HALODelay. The NOCTURNE reverb allows players to create expressive, touch-sensitive bloom that trails effortlessly behind every note, without the cross-talk from echoes.
Developed in collaboration with Andy Timmons, the NOCTURNE from Keeley Electronics is a flagship reverb pedal that redefines ambient tones. With three reverb soundscapes shaped by just four intuitive controls, it’s designed for effortless onstage control and sonic depth for plug & play types. Advanced users will appreciate its remote switching, expression pedal support, preset storage, and full MIDI integration for maximum flexibility.

The NOCTURNE pedal gives you three new reverb modes – Nocturne, Spring, and Plate – each designed to be the guitar and amp’s perfect companion. The Plate reverb is based on Keeley’s extensive analysis and modeling of the stereo tube plate reverb that was in Austin City Limits studio since the mid-1970s. The Nocturne’s Spring reverb features their finest sounds based on both stand-alone reverb tanks and tube amplifier combos.
