Keeley Electronics Eccos Delay & Looper

The Keeley Eccos took nearly four years to develop – a long time for a pedal!

But then the Eccos isn’t a conventional delay pedal. It’s the result of Keeley’s Quad 24/56-bit Dream DSP platform, and the thing that came out of it was a new type of delay sound. The flanged tape delay.

Tape flanging on the Eccos is not a flanger effect added to a delay.

It’s a modulation of the delay itself. The echoes are flanged in a way that creates movement in the repeats rather than a static echo that fades out. The shape and tone of each repeat is constanly changing to give a lush quality to the trail.

The looper has a full feature set. Two minutes in mono or sixty seconds in stereo. Reverse mode. Half-speed mode. One-shot playback. Sound on Sound mode which lets you record new layers without erasing the original loop. This recreates the feel of reel-to-reel layering. The looper and delay work independently so you can both simultaneously or use either alone.

It was voted one of Delicious Audio’s Best Pedals of 2020.

The Delay Section

Up to 1.5 seconds of stereo tape-flanged delay. Controls for Time, Feedback, Rate and Depth shape the delay and modulation independently. Three memory presets store all delay settings. Expression pedal control is assignable over any parameter in any direction. Trails mode allows the delay to continue fading naturally after bypass. Stereo True Bypass or Trails is switchable on the fly.

The Looper Section

A full-featured stereo looper with two minutes in mono or sixty seconds in stereo. The looper footswitch handles Record, Play, Overdub, and Stop. Reverse and Half-Speed modes change the playback character. One-Shot mode triggers the loop to play once then stop.

Sound on Sound mode lets you record new layers while the existing loop gradually reduces in volume over time — recreating a vintage reel-to-reel technique where loops accumulate naturally. Set the decay rate by holding the FDBK knob and adjusting the Depth control.

Controls

• Time: Adjusts delay time – 5ms to 1.5 seconds.
• Blend: Adjusts wet and dry
• Depth: Depth of delay modulation, up to 13ms. High settings give chorus modulation
• Feedback (FDBK): Adjusts the number of delays or repeats
• Rate: Controls the speed of the modulated delay trails, from 0 to 15Hz.
• Secondary controls, accessed by holding FDBK while turning other knobs:
  • Manual (Flanger Time): subtly changes the delay time of the flange- 0-13ms.
  • Vibe (Modulation Style): controls the blend between pitch vibrato and flanging repeats
  • Tone: shapes the tone of the repeats, from a bright high-pass sheen to a warm, tape-style roll-off.
  • Regen (Flanger Regeneration): controls the amount of flanger feedback.
  • Subdivisions: Set this by holding FDBK and toggling the Mode switch, cycling through Quarter, Dotted Eighth, Eighth, or Triplet.
  • Looper mode reassigns two of the footswitches: Bypass becomes Record/Play/Stop, and the Reverse/Half Speed switch does exactly that. Feedback also doubles as Undo/Redo (hold for 1 second) and preset save/select in that mode.
