Boss DD-20 Effects Pedal : Review

DD-20

All the necessary is available

A complete machine. Flexibility and quality are remarkable. The front panel is really complete. Let's see all the available options.

Control panel
  • E. Level
  • It modifies the effect volume.

  • Feedback
  • It adjusts the number of the repeats.

  • Tone
  • Substantially, the equalizer. It modifies the highest frequencies.

Mode

The DD-20 provides eleven ready-to-use Delays that can be choosen with this knob. Let's see the list of the possible options.

  • SOS
  • It continuously repeat a previous recording with a maximum length of 23 seconds. If you want you can use the Overdub function, so to add new material to the recording.

  • Twist
  • Aggressive. Particularly suitable to the distortion.

  • Warp
  • It simultaneously acts on the Feedback and on the effect volume. It is much particular. A bit confused, perhaps, but in some circumstances it can be useful.

  • Tape
  • It emulates the Roland RE-201.

  • Analog
  • The emulation of the Boss DM-2.

  • Standard
  • For a general purpose.

  • Dual
  • 2 Delays, one short and one long, are connected in series.

  • Pan
  • It moves left and right.

  • Smooth
  • It creates a reverb.

  • Modulate
  • It adds a wave to the sound and creates a warm delay.

  • Reverse
  • A classic, but little usable.

D. Time

The duration of the effect. There are two modalities. Pushing on the knob activates some advanced functions, while turning it simply modifies the value of the parameter.

Memory Section

The DD-20 provides the possibility of storing the Delays created by the user.

  • Memory Number Indicators
  • The active selection.

  • Select

Rear panel

Very complete. Two inputs, to connect a guitar or an effects processor. Two outputs. It can be connected to a guitar amp, a mixer, a recorder. One output for the headphones, one input for an additional control pedal and the AC adaptor jack. The AC adaptor, PSA, is sold separately.

Final opinion

The DD-20 is an excellent product. The quality of the sound is really remarkable. All the necessary for a good job is present. The manual is much complete and explains all the functions of the pedal. As regards the price, my personal opinion is that it is valid, but, above all, used can be really a bargain.

Effects (Pedals and Floorboards)

    TS9 Tube Screamer
  • Distortion | Ibanez
    TS9 Tube Screamer

    The Reissue of a very famous Ibanez Overdrive. In effect, there are many similes between the two models: components, colour and controls are those of the original version. Very transparent and silent.

  • CS-3
  • Compression | Boss
    CS-3

    A pedal that can be a good solution for the guitar, but also for the bass. It is a compressor but, with a correct use of the controls, it can work as a limiter. The price is valid.

  • Turbo Flange
  • Flanger | Digitech
    Turbo Flange

    The mix between Regen and Type can generate an infinite number of combinations. 7 possible selections: Voice 1, Voice 2, Voice 3, Rise/Fall, Trig Up, Trig Down, Step. 2 Inputs and 2 Outputs, even with a speaker emulator.
