Boss RV-6 Settings Guide

Eight reverb types in a compact unit. Industry standard for every context from subtle room ambience to cavernous shimmer.

Used by: David Gilmour, The Edge, John Mayer, Carlos Santana

The best Boss RV-6 settings start with: Mode at 3/10, Time at 4/10, Tone at 5/10, Level at 4/10. Adjust from there based on your amp, guitar, and room volume. For Blues: Mode 4/10, Time 3/10, Tone 5/10, Level 3/10.

What Each Control Does

Mode
Room
Shimmer
Reverb type: Room, Hall, Plate, Spring, Modulate, Dynamic, Shimmer, +Delay.
Time
Short
Infinite
Reverb decay time. Shorter = intimacy; longer = space.
Tone
Dark
Bright
Colour of the reverb tail. Darker = vintage; brighter = studio.
Level
Dry
Wet
Mix of reverb vs dry signal.

Settings by Genre

Blues
Mode4
Time3
Tone5
Level3

Spring reverb, moderate time, subtle level. The vintage spring character suits single-coil pickups perfectly — slapback + spring is the Fender clean sound.

Classic Rock
Mode2
Time4
Tone5
Level4

Hall reverb, medium decay, moderate level. Adds dimension to Les Paul and humbucker tones without washing out the mid-range character.

Country
Mode4
Time2
Tone6
Level3

Short spring reverb with bright tone — the traditional Fender country sound. Keep level subtle so the reverb feels like the amp breathing rather than an obvious effect.

Ambient
Mode3
Time8
Tone5
Level6

Hall or Plate with long decay. Let chords wash into each other.

Jazz
Mode1
Time3
Tone4
Level2

Room reverb, short decay, subtle. Jazz players often prefer minimal reverb — the room sound should be heard but never identified as "reverb".

Mode3
Time5
Tone5
Level4

Gilmour uses hall/plate reverb as a core texture — not a wash, but a dimensional presence behind leads. His reverb runs in the effects loop after delay, at moderate level so it supports the delay repeats without competing. On slow solos like Comfortably Numb, reverb time is generous (decay ~5); for faster lines it tightens up.

Mode3
Time6
Tone5
Level3

The Edge uses reverb as a secondary ambience layer behind heavy delay — the delay is the primary effect, reverb adds the sense of a large space. He keeps reverb level lower than the delay level so they don't compete. Hall mode at medium decay. The combination of specific delay times + light reverb creates the U2 "stadium" sound.

Mode4
Time3
Tone6
Level3

Mayer uses spring reverb on his Fender amps — the RV-6's spring mode captures this. Short decay, moderate level, bright tone. On slow blues the reverb time increases; on rhythm playing it stays short and dry-adjacent. The goal is a vintage Fender combo feel, not a wet effect.

Mode2
Time5
Tone5
Level5

Santana uses hall reverb at moderate level as a core sustain tool — the reverb tail extends his sustain artificially and creates the smooth, singing note quality. His lead tone without reverb loses much of its vocal character. Level is higher than most rock players would use.

Tips & Common Mistakes

  • Spring reverb (Mode 4) suits single-coil pickups and classic rock/blues best. Plate suits any pickup type.
  • Place reverb last in the signal chain (or in effects loop). Reverb before overdrive muddies the sound.
  • The Dynamic mode automatically reduces reverb during playing and lets it bloom in pauses — professional technique for keeping busy passages clear while chords ring out.
  • Level at 3–4 makes reverb feel like the room. Level at 6+ makes reverb an obvious effect. Most guitarists want the former.
  • The +Delay mode combines reverb and delay — a useful performance shortcut but gives less precise control than running dedicated reverb and delay pedals separately.
  • The Shimmer mode adds an octave-up pitch layer to the reverb tail — best used with long Time and moderate Level so it swells in gradually rather than competing with the dry signal. Pair with a volume pedal for evolving ambient textures.
  • Set Tone darker (2–3) for warm vintage reverb into bright amps or single-coil guitars. Brighter Tone (7–8) suits darker humbuckers or warm amplifiers — balance the system's total character rather than judging the pedal in isolation.
  • Short Time (1–2) in Room mode creates subtle acoustic room presence for a direct-injected guitar signal — it prevents a DI tone from sounding sterile without adding an obvious effect. Useful for studio recording where a natural "live in room" feel is needed.
