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
