Keeley 30ms Double Tracker overview

  • 1Description

Bring a classic studio technique to your rig with the compact 30ms Automatic Double Tracker Pedal from Keeley. With three distinct operating modes, a TRS stereo output, and controls over tuning, delay time, and reverb, this pedal is not just a super-short delay, it's a powerful tone-shaping tool. Using the onboard controls, you can modify your guitar's tone for adding subtle thickness or over-the-top warbling for a wall of sound when operating in stereo.

Operating Modes

Dimension Mode
Produces 2 voices, one delayed by up to 30 milliseconds, and both voices are slightly detuned for a wider sound, the Tuning control adjusts the pitch of the detuning
Abby Mode
Approximates the double tracking effect pioneered by British studios in the 1960's where one voice is delayed with a modulation effect reminiscent of manually slowing a tape machine
Slapback Mode
Produces an adjustable classic slapback delay, which can be from 30 to 120 milliseconds in length and in addition to the 2 adjustable doubled voices
Mono/Stereo Output
The output jack of the 30ms is a TRS stereo jack which, when used with a TRS cable, splits the affected signal for stereo imaging, great for huge tones in the studio and on stage. DIP switches under the rear panel of the pedal enable you to configure the first channel's output as well as activate Double Track Pro mode which changes the reverb control function to become a second tuning control.


Tuning: Controls the tuning of the double-tracked voices up to ±30 cents in Dimension and Slapback modes. In Abby mode, this controls the modulation rate and depth
Time: Controls delay time from 0-30 ms or 30-120 ms in Slapback mode
Reverb: Controls the amount of reverb, modeled after vintage studio echo-chamber-style reverb with roll off at 600 Hz and 10 kHz
Level: Controls the final output level of the pedal
