30ms Double Tracker

The Keeley 30ms Double Tracker is a versatile stereo effect pedal designed to create thicker, fuller sounds for instruments. It offers an array of studio- style doubling effects, making it a powerful tone-shaping tool. The pedal features three distinct operating modes:

1. Dimension Mode: Produces two voices, with one delayed by up to 30 milliseconds, and both voices slightly detuned for a wider sound. The Tuning control adjusts the pitch of the detuning.

2. Abby Mode: Approximates the double tracking effect pioneered by British studios in the 1960s, where one voice is delayed with a modulation effect reminiscent of manually slowing a tape machine.

3. Slapback Mode: Produces an adjustable classic slapback delay, which can range from 30 to 120 milliseconds in length, in addition to the two adjustable doubled voices.

The pedal offers mono/stereo output, with the output jack being a TRS stereo jack. When used with a TRS cable, it splits the affected signal for stereo imaging, suitable for creating huge tones in the studio and on stage.

Key Controls:
- 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.
