M104 Analog Delay

Inspired by Moog® Moogerfooger MF104M Analog Delay

THE'M104 Analog Delay is a compact analog delay with built-in modulation.

  • Main features:
  • Repetitions dark and soft
  • Built-in chorus-type modulation
  • Light saturation (drive)
  • Sound vintage and musical

Perfect for: Rock Blues Lead Ambient vintage

SOUND CHARACTER

  • Delay warm and round
  • Highs attenuated progressively
  • Soft modulation
  • Light analog saturation

Smoother than the BBD Delay

Control Parameters

SyncY/N

Sync to BPM:

  • Y → musical divisions
  • N → manual time
Delayms

Repetition time:

  • 80–120 ms → slapback
  • 300–450 ms → rhythmic
  • 500+ ms → ambient
Feedback%
  • Number of repetitions:
  • Low → few
  • Medium → sustain
  • High → many repetitions

Above 65–70% → almost infinite

Mix%

Amount of Delay:

  • 0–20% → light
  • 25–35% → standard
  • 40%+ → obvious
LFO Rate%

Modulation speed:

  • Low → slow
  • High → fast

Repetition movement

LFO Depth%

Modulation intensity:

  • Low → light
  • High → more noticeable

“Wow/flutter” effect

Drives%

Saturation amount:

  • Low → clean
  • Medium → hot
  • High → slightly distorted

Adds analog character

TailsY/N

Bypass behavior:

  • Y → delay continues
  • N → immediate stop

Pro Tips

  • Want vintage → turn up Drive
  • Want movement → raise LFO Depth
  • Want clean → lower Drive
  • Want ambient → turn up Feedback + Mix

Sweet spots:

  • Delay: 400 ms
  • Feedback: 35%
  • Mix: 30%
  • Drive: 55%
  • LFO Depth: 25%

Perfect analog sound
