The Keeley 30ms Double Tracker is a studio-inspired guitar effects pedal designed to replicate the legendary double-tracking techniques pioneered in classic recording environments. Serial Number B0875 represents an early production unit, built with Keeley Engineering’s signature attention to tonal fidelity and precision.Inspired by the automatic double tracking (ADT) techniques developed in iconic studios, this pedal allows players to create rich, dimensional tones without the need for multiple takes. It delivers everything from subtle doubling and slapback to expansive stereo-style spread, making it a powerful tool for both live performance and recording.With intuitive controls and high-quality analog signal processing paired with digital time manipulation, the 30ms Double Tracker provides a natural, organic feel that enhances the core tone rather than masking it.Key Features Authentic double-tracking effect based on classic studio techniques Short delay range (0–30ms) for realistic doubling and spatial enhancement Stereo-style widening from a mono signal Slapback delay capability for vintage tones True bypass switching for signal integrity High-headroom design suitable for a wide range of instrumentsSpecificationsGeneral Model: Keeley 30ms Double Tracker Serial Number: B0875 Manufacturer: Keeley Engineering Effect Type: Double tracking / short delay / ADT simulation ControlsTime: Adjusts delay from 0 to 30 milliseconds Blend: Mix between dry and effected signal Dimension: Controls spatial spread and modulation depth Mode Switch: Selects between doubling, slapback, and widening modes Audio Signal Path: Analog dry signal with digital delay processing Frequency Response: Full-range, transparent response Dynamic Range: High headroom, low noise operation Connectivity Input: 1 x 1/4” mono input Output: 1 x 1/4” mono output (stereo-like effect from single output) Power Power Requirement: 9V DC (center-negative) Current Draw: Approx. 65 mA Battery Operation: Not supported Construction Enclosure: Compact metal chassis Finish: Standard Keeley branded enclosure Switching: True bypass footswitch
