30 ms Double Tracker

The Keeley 30ms Automatic Double Tracker is a stereo double tracking effects pedal designed for thickening and enhancing instrument sound using a blend of studio-style doubling, reverb, and detuned modulation. This Keeley effects pedal provides three main operating modes: Dimension, Abbey, and Slapback. The Dimension mode enables the creation of up to two separate detuned voices, emulating the unpredictable quality of studio double-tracking without an LFO. Abbey mode simulates parallel tape decks to produce a wide, tape chorus texture. Slapback mode adds a double-tracked echo for short delay effects. The built-in Abbey chamber reverb is available in any mode, and the unit can be used in mono or stereo configurations. The pedal is compatible with bass instruments, features true bypass switching, and supports stereo output. **Features:** - Stereo double tracking effects pedal with mono or stereo operation - Built-in Abbey chamber reverb emulating Studio Two - Three selectable modes: Dimension, Abbey (tape chorus), and Slapback (echo/delay) - Adjustable tuning and delay controls for each tracked voice - True bypass switching for clean signal when bypassed - Compatible with bass instruments
