Boss DD-6 Digital Delay Effect Pedal

The DD-2 was Boss's first compact digital pedal in 1984. It featured an IC chip that replaced most of the conventional circuitry. The DD-3 from 1986 was virtually identical but more affordable. The DD-5 from 1995 offered delay times of up to two seconds, more than twice the maximum 800 milliseconds of the DD-3. It also offered eleven different delay modes. Reverse delay was available for the first time. The DD-6 was launched in 2002 and was expanded with additional functions.

With the DD-6, the maximum delay time was increased to 5.2 seconds (in long delay mode), and the tap tempo function was accessible via the integrated pedal switch. The hold function offers a recording time of 5.2 seconds as well as sound-on-sound overdubbing, plus true stereo inputs and outputs. In addition, a warp mode was introduced, which produces tape-like pitch and oscillation effects by holding down the pedal switch.
