The Keeley Engineering 30ms Automatic Double Tracker pedal can be used in mono with a built-in "Abbey Verb" reverb control, or in stereo like the Double Tracker Pro. The 30ms offers modified and detuned effects like a chorus pedal might sound, only without the regularity of an LFO in Dimension mode. In this mode, you have the ability to create up to two different voices for a dual-track stereo field. The user controls the setting and delay for results that are stunning in mono or, with two amplifiers, in sublime stereo. The Abbey mode offers something more similar to a conventional chorus in that it simulates synchronized tape recorders running in parallel with varying tape speeds. Stereo or mono, this mode offers players a large, lush sound without sounding like a conventional chorus pedal. Finally, the Keeley team created a unique Slapback mode for rockabilly sounds. Slapback is now a dual-track echo with both voices modified. Add the Keeley Abbey verb to this mode to create stunning new effects.
In Stereo Double Tracker Pro mode, the unit removes the reverb channel in favor of full control over the dual-tracked voices. Each of the two voices can be adjusted up to 30 cents high or flat. These voices are then delayed by up to 30 milliseconds for subtle to very distinctive overdubs. Via internal switches, users can program the wet output to have dry, affected sounds or just the effect, giving them true dual tracking in stereo - live.
