Hardly any of today's guitarist would want to miss the benefits of a delay pedal, with digital delays definitely leading the way. The DDL20 is a straightforward digital delay that offers all of the basic featuers that make this such a popular effector. With its superior bandwidth of 16kHz and a wide range of delay times from 8ms to 1024ms, the DDL20 will provide you with all of the delay effects necessary for modern guitar work, including everything from doubling to long delay. Needless to say, the delay sound is what you would expect from a high-quality digital effector, superbly ambient and clear.


The original signal (such as a guitar sound) is converted into a digital representation of that sound. In this form it can be manipulated without further degradation of quality. Some change in tonality is unavoidable, but the high resolution or "sample rate" of the new Ibanez series keeps this to an almost inaudible level. The DDL20 allows manipulation of the signal by setting up a time period to elapse before the sound is "played back". Of course it is converted back into analog form first.


The effects based on delay are many and varied, from doubling and slap echo to long delay, from flanging and phasing to chorus. All use different delay times and levels of feedback (Repeat). In order to facilitate selection of the desired type, the DDL20 has effect names printed above the corresponding delay times to serve as a guideline. Try the following setting for a doubling effect, often used to give the impression of two instruments being played simultaneously and to thicken the sound. First, set Mode to 2, turn repeat all the way down to 0 for just one repeat, and adjust D-Level to a large value around 8 to 9. Your guitar will now sound fatter, more live and ambient, especially if you make use of the stereo outputs connected to two amps for a full, three-dimensional stereo sound. Though this setting does not make a dramatic change in the timbre of the guitar, itis extremely effective when used at the right time and with deliberate restraint, for instance during melodious solos.
