Boss RE-20 Space Echo Settings Guide
Digital emulation of the Roland RE-201 tape echo — one of the most recorded echo effects in history. Heard on virtually every reggae record ever made and countless dub, surf, and psychedelic recordings.
Used by: David Gilmour, The Edge, Tom Petty
The best Boss RE-20 Space Echo settings start with: Repeat Rate at 5/10, Intensity at 3/10, Bass at 6/10, Treble at 4/10. Adjust from there based on your amp, guitar, and room volume. For Reggae / Dub: Repeat Rate 6/10, Intensity 5/10, Bass 7/10, Treble 3/10.

Settings by Genre
Long Repeat Rate with multiple Intensities and warm character (high Bass, low Treble) — the Studio One / King Tubby dub echo. The RE-20's self-oscillation in controlled amounts produces the cascading, warping echo that defines dub music. Bass heavy, Treble dark for the characteristic warm tape repeat.
Short to medium Repeat Rate, moderate Intensity — the surf reverb predecessor. The RE-201 was used before spring reverb became dominant. Three-head mode with moderate settings produces the warm multi-tap echo of vintage Dick Dale-adjacent recordings.
Very short Repeat Rate, single Intensity — warm tape slapback echo. The RE-20's tape character on short single-repeat settings produces a more musical, filtered slapback than digital single-repeat delay.
Moderate Repeat Rate, warm character, few repeats — the RE-20 as a classic rockabilly/blues lead echo rather than a rhythmic effect. The tape character under lead single notes adds the vintage depth of an echo chamber without rhythmic complexity.
Artist Settings
Documented settings used by professional guitarists on this unit.
Gilmour used the original RE-201 on early Pink Floyd recordings as part of his foundational delay setup — alongside the Binson Echorec. The RE-20's warm, multi-head character suits his approach of multiple overlapping delay times. Bass and Treble set for warmth, Intensity at 4 for musical trailing echoes.
The Edge used tape echo units in early U2 recordings and has returned to them for specific tonal purposes. The RE-20's warm, character-rich repeats produce a different feel from his usual digital delay — less precise, more organic. His early recordings like October and October have tape-echo-adjacent character in the guitar processing.
Petty used tape echo for its character-adding qualities on clean Fender tones — a warm single-repeat that extends notes without adding obvious rhythmic delay. The RE-20 at these settings produces the 1950s-adjacent echo that classic rock's relationship to early rock'n'roll required.
Tips & Common Mistakes
- The RE-20's self-oscillation is a performance technique, not a malfunction — bringing Intensity to maximum with Repeat Rate varied creates the cascading, warping echo effect of classic dub and psychedelic recordings.
- The Mode selector changes the tape head combination — experiment with all modes before adjusting Rate and Intensity. Each mode produces fundamentally different timing patterns.
- Set Treble below noon for the most authentic tape character — original tape echo machines darkened significantly on each repeat. A bright RE-20 sounds more like a digital delay.
- The RE-20 is one of the most intuitive pedals for setting by ear rather than by numbers — let the Repeat Rate interact with the song tempo naturally rather than calculating exact ms.

For Reggae / Dub: Repeat Rate 6/10, Intensity 5/10, Bass 7/10, Treble 3/10.

The RE-20's self-oscillation in controlled amounts produces the cascading, warping echo that defines dub music. Bass heavy, Treble dark for the characteristic warm tape repeat.
For Surf: Repeat Rate 4/10, Intensity 3/10, Bass 5/10, Treble 4/10. Short to medium Repeat Rate, moderate Intensity — the surf reverb predecessor. The RE-201 was used before spring reverb became dominant. Three-head mode with moderate settings produces the warm multi-tap echo of vintage Dick Dale-adjacent recordings.
Mode: Playback head combination — different modes activate different tape heads for different repeat patterns and characters. (Echo 1 to Echo + Reverb). Repeat Rate: Delay time. Interacts with Mode — the tape head spacing determines actual delay times at any Rate setting. (Fast to Slow). Intensity: Feedback — number of repeats. Above 3 o'clock: entering self-oscillation territory, which on the RE-201 is a musical, cascading swell. (Single to Self-Oscillation). Bass: Tone of the echo signal — warmer at higher settings, brighter at lower. (Thin to Warm). Treble: Upper-frequency content of the echo. The original RE-201 darkened with each repeat — set Treble below noon for the authentic warm-tape character. (Dark to Bright)
