The Keeley Memphis Sun is a studio-grade lo-fi reverb, echo, and double-tracker pedal designed to capture classic rock-and-roll tones with modern versatility. This three-in-one effects pedal combines room reverb, automatic double tracking (ADT), and echo in a single compact unit. The Room Reverb simulates a vintage 33' × 18' asbestos-tiled space with natural compression and harmonic coloration inspired by classic RCA 77 microphones. The Sun Mode delivers warm, vintage-voiced double tracking with up to 180ms of delay time—perfect for everything from subtle ADT to slapback echo. The Echo 600 mode offers up to 666ms of delay with multi-stage filtering and tape-like harmonic saturation for authentic rock-and-roll character. Each mode features intuitive controls: Time adjusts pre-delay or echo duration, Regen/Mod shapes tone and modulation, and Reverb sets depth. Whether you're chasing neo-vintage tones or exploring experimental soundscapes, the Memphis Sun delivers the warmth and character of classic studio gear in a pedalboard-friendly format.
