Delay Types for Guitar: Slapback to Dotted Eighth
Delay is the most musical effect on a pedalboard because it plays in time with you, from a single rockabilly slap to cascading rhythmic patterns that turn one guitar into three.
The two questions that matter: what character of repeat do you want, and what time value serves the song. This guide answers both, with concrete settings.
Analog and Tape: Warm and Blurry
Older delay technologies degrade each repeat, and that flaw is the charm.
- Analog bucket-brigade circuits darken every repeat, so echoes tuck neatly behind your playing.
- Tape-style delay adds wobble and gentle saturation for a vintage haze.
- Both excel at thickening solos without cluttering them.
- High feedback settings self-oscillate into swelling noise, a classic transition trick.
Digital: Clean and Precise
Digital delay repeats exactly what you played, as long and as clearly as you like.
- Choose digital when repeats must stay intelligible, as in rhythmic pattern playing.
- Tap tempo and note subdivisions keep the effect locked to the song.
- Most modern digital pedals also model analog and tape voices convincingly.
- Trim the mix; pristine repeats feel louder than dark ones.
Three Classic Recipes
These three settings cover most of recorded music.
- Slapback: 80 to 140 ms, feedback 1 for a single repeat, mix 3 to 4. Rockabilly, country and indie vocals-style snap.
- Quarter note: 60000 divided by the BPM gives the time in ms; feedback 3 to 4, mix 2 to 3.
- Dotted eighth: quarter-note time multiplied by 0.75; feedback 3 to 4, mix 3 to 4 for chiming, interlocking lines.
Placement and Housekeeping
Where the delay sits decides how clean it sounds.
- Run delay after drive pedals, or in the amp effects loop with a driven amp.
- Delay before reverb, almost always.
- Use less mix live than at home; rooms blur repeats on their own.
- Practice tapping tempo mid-song; it matters more than any preset.
Frequently asked questions
How do I calculate dotted-eighth delay time?
Take 60000 divided by BPM for the quarter note, then multiply by 0.75. At 120 BPM that is 375 ms.
Should delay go in front of the amp or the loop?
Into a clean amp, the front is fine. Into a driven amp, use the loop so repeats stay clear.
Analog or digital for a first delay pedal?
A digital pedal with tap tempo and an analog-voiced mode gives you both characters in one box.
What is self-oscillation?
Feedback set so high that repeats regenerate endlessly, swelling into pitchable noise. Great for transitions; watch your volume.
