How to Use a Reverb Pedal — Settings, Types, and Placement Explained
Reverb is the most natural-sounding effect in guitar music — so natural, in fact, that many players don't even notice when it's present. When reverb is done well, it simply sounds like the guitar exists in a real space. When it's done badly, it sounds like you're playing in a bathroom.
Understanding reverb is about understanding space. Before electronic reverb, the sound of a guitar in a room was determined entirely by the room's physical properties. A cathedral creates long, lush reverb. A closet creates almost none. A recording studio live room sits somewhere in between. Reverb pedals let you place your guitar in any of these spaces artificially — and control the exact parameters.
This guide covers every control, every type, and every decision involved in using reverb well.
Why Reverb Matters
Try playing your guitar completely dry — no reverb, no effects of any kind, directly into your amp in a dead room. The sound is flat, thin, and lifeless. Add even a small amount of room reverb, and suddenly the guitar has dimension. Notes feel like they exist in a physical space rather than floating in a void.
Reverb does two things that nothing else can:
- It adds depth — making the guitar feel further away or closer, larger or smaller
- It provides sustain cushioning — notes decay into the reverb tail rather than cutting off suddenly
Almost every professional guitarist uses reverb, even when it is not audible as a distinct effect. The question is not whether to use it, but how much and what type.
The Core Controls
Different reverb pedals have different labels, but the fundamental controls are consistent across all of them.
Mix (also called Blend, Wet/Dry, or Reverb Level)
Mix controls the ratio of the reverb signal to the dry signal. At zero, you hear only the dry guitar. At 100%, you hear only the reverb. In practice, most guitar players set mix between 15% and 40%.
Starting point: 20–25% for general use. This adds space without washing out the note definition.
Higher mix (40%+): Suits ambient music, large-hall lead guitar, or atmospheric passages where the reverb is part of the texture rather than just a background.
Lower mix (10–15%): Suits fast music, country, or any context where note clarity and separation matter more than space.
Decay (also called Time, Length, or Reverb)
Decay controls how long the reverb tail lasts before it fades to silence. Short decay simulates a small, dead room. Long decay simulates a large hall or cathedral.
Short decay (1–2 seconds): Notes have space but don't blur together. Good for rhythm playing.
Medium decay (2–4 seconds): The all-purpose range. Notes have room to breathe; consecutive notes don't wash together.
Long decay (5+ seconds): Lead guitar and ambient playing. Notes bloom and sustain into the reverb. Consecutive notes start to blur, which can work atmospherically but muddies rhythm playing.
Pre-Delay
Pre-delay is a short delay before the reverb effect begins. It separates the attack of each note from the start of the reverb, preserving the punch and definition of the initial note.
Without pre-delay: the reverb starts immediately, washing into the attack. With pre-delay (10–30ms): the attack is heard clearly; then the reverb tail begins.
Pre-delay is particularly important at higher mix settings. If your reverb sounds washy and undefined, try adding 10–20ms of pre-delay before increasing decay or reducing mix.
Tone (or Damping)
Some reverb pedals have a tone control that affects the frequency content of the reverb tail. Lower settings produce darker, more natural-sounding reverb (high frequencies decay faster, simulating soft wall materials). Higher settings produce brighter, more present reverb.
For natural room sounds: Set tone at 50% or lower. Natural reverb has less high-frequency content than the dry signal.
For shimmer or special effects: Higher tone settings emphasise the upper frequencies in the reverb tail.
Reverb Types Explained
This is where reverb gets interesting. Different reverb types don't just vary in size — they have genuinely different characters that suit different music.
Spring Reverb
Spring reverb uses an actual physical spring — a coil of metal wire — inside the amplifier or pedal. The audio signal travels through the spring via transducers, and the spring's mechanical resonance produces the reverb effect.
Spring reverb has a characteristic "boing" quality — slightly metallic, dripping, with a pronounced resonance on the bass frequencies. This is the sound of vintage Fender amplifiers, Hawaiian guitar, surf music, country, and 1960s rock and roll. It is the most distinctively "guitar" reverb type.
Best for: Surf, country, rockabilly, blues, classic rock, any music that wants a vintage character.
Famous uses: Fender Reverb amp reverb on most 1960s–1970s rock recordings. Dick Dale's surf guitar tone. The Shadows.
Setting notes: Spring reverb sounds best at moderate mix levels — the "boing" quality becomes unnatural at high levels. Set mix at 20–35%, decay at medium.
Room Reverb
Room reverb simulates a small, naturally reflective space — a recording studio live room, a rehearsal space, or a small venue. The tail is relatively short and dense.
Room reverb is the most neutral and versatile reverb type. It adds space without imposing a strong character. For players who want reverb present but subtle, room is the go-to choice.
Best for: Any style where you want a natural presence without a specific character. Jazz, pop, classic rock rhythm playing.
Setting notes: Room reverb works at all mix levels. Short-to-medium decay. Low pre-delay or none.
Hall Reverb
Hall reverb simulates a large concert hall — the long, smooth decay of a symphonic performance space. The tail is long, smooth, and expansive.
Hall reverb is the standard for lead guitar in rock and pop contexts. It allows notes to bloom and sustain beautifully. It adds grandeur and scale to solo passages. Used correctly, it makes lead guitar sound expensive.
Best for: Lead guitar, clean arpeggiated passages, ballads, Pink Floyd-style atmospherics.
Famous uses: David Gilmour's lead tone on "Comfortably Numb," "Shine On You Crazy Diamond." Kenny Burrell's jazz guitar. Most stadium rock lead guitar.
Setting notes: Hall reverb needs enough decay to be audible (2+ seconds) but can become washy fast. Use pre-delay (15–25ms) to preserve note definition. Mix at 25–40%.
Plate Reverb
Plate reverb is a studio technique that uses a large metal plate with transducers attached. The plate's physical resonance creates a smooth, dense reverb with a slightly metallic, bright quality.
Plate reverb was a standard studio tool from the 1950s through the 1980s. Its character is different from both spring and room — smoother than spring, more present than hall. It has a slightly grainy, almost textured quality.
Best for: Studio recording simulation, when you want reverb with density and presence. Some rock and pop players use plate pedal settings for a distinctive studio feel.
Famous uses: Widespread in 1980s recording — many of the arena rock guitar sounds of that era used plate reverb.
Shimmer Reverb
Shimmer adds pitch-shifted harmonics (usually an octave up, sometimes a fifth) to the reverb tail. The result is an ethereal, synthesiser-like quality — the guitar seems to sustain upward into a celestial register.
Shimmer reverb is a modern creation, popularised by the Eventide H3000 and later by reverb pedals with digital processing. It is not naturalistic — there is no acoustic equivalent. It suits ambient guitar, worship music, post-rock, and experimental contexts.
Best for: Ambient, worship, experimental, atmospheric interludes.
Setting notes: Works best with longer decay and higher mix. The pitch-shifted tails need space. Sounds most effective on sustained notes rather than fast passages.
Famous Reverb Sounds and How to Approximate Them
David Gilmour — "Comfortably Numb" Solo
Hall reverb with a long tail. Mix: 35–40%. Decay: 4–5 seconds. Pre-delay: 20ms. The reverb is a significant part of the tone's expansiveness. Combined with long, expressive sustained notes, the reverb creates the impression that the solo is echoing across a stadium.
Use a hall reverb setting on any modern reverb pedal. Strymon BigSky, Boss RV-6, and TC Hall of Fame all have hall settings that approach this.
Jimi Hendrix — "Little Wing" Clean Intro
Spring reverb, moderate level. Mix: 25%. Decay: medium-short. The natural Fender amp spring reverb creates just enough depth to give the clean chord work air. It is not dramatic — it is simply present.
The Edge (U2) — Atmospheric Clean Parts
Reverb plus delay combination — the two effects stack into each other's tails. Hall reverb with a very long tail creates a wash that the delay repeats multiply into. Mix very high (50%+). This is a texture, not a transparent effect.
Country Clean Tone
Spring reverb at low-moderate level. Mix: 15–20%. Decay: short. The spring adds sparkle and "slap" to the clean Telecaster or Stratocaster sound without imposing atmosphere. Country reverb should be felt more than heard.
Position in the Signal Chain
Reverb always goes last in the signal chain — after all drive, modulation, and delay effects:
Guitar → Tuner → Drive/Overdrive → Modulation (Chorus/Phaser) → Delay → Reverb → Amp
Why reverb goes last: Reverb applies to whatever signal enters it. If reverb is before overdrive, the drive effect distorts the reverb tail — creating a cloudy, indistinct mess. If reverb is before delay, the repeats are washed in reverb, which quickly becomes muddy. Reverb last means a clean, defined reverb on the finished, processed signal.
Exception — in the amp effects loop: If your amplifier has an effects loop, reverb often belongs there (in the loop) rather than in front of the amp. The effects loop sits between the preamp and power amp stages. Running reverb in the loop applies it after the amp's preamp gain stage, which often produces cleaner, more natural reverb. This is especially relevant for players using high-gain amp channels.
Reverb vs Built-In Amp Reverb
Many guitar amplifiers include onboard spring reverb. The question is whether an external pedal is necessary.
If your amp has good spring reverb: It may be all you need for most styles. Fender spring reverb, in particular, is excellent. External pedals offer variety (hall, plate, shimmer) and more precise control, but are not required.
If your amp's reverb is weak or absent: An external pedal is worthwhile. The reverb built into lower-end solid state amps is often digital and limited.
Advantages of external pedals:
- More reverb types (hall, plate, shimmer, room)
- More precise control over each parameter
- Can be switched on and off during a set without touching the amp
- Can run in the effects loop of any amp
Pedal recommendations by budget:
- Under £80: TC Electronic Hall of Fame 2 (excellent hall algorithms, TonePrint programmable)
- £100–150: Boss RV-6 (seven reverb types, reliable, stage-tested)
- £200–300: Strymon BigSky MX (studio-quality algorithms, programmable presets)
- Boutique: Eventide Space (professional studio standard, vast algorithm selection)
Common Reverb Mistakes
Too much decay on rhythm parts: Fast chord changes blur together. Keep decay short for rhythm; longer for lead.
No pre-delay: Notes lose definition and the attack gets washed. Always try adding 10–20ms of pre-delay when mix is above 30%.
Wrong type for the style: Hall reverb on country sounds unnatural. Spring reverb on ambient music sounds incongruous. Match the type to the context.
Reverb before drive: The most common routing mistake. Always reverb last (or in the effects loop for high-gain players).
No reverb at all on a direct recording: Playing direct into a recording interface with no reverb sounds completely unnatural. Even a very subtle room reverb (mix: 10%) is needed to give the dry signal any dimension.
Frequently Asked Questions
Does my amp's built-in reverb make a reverb pedal unnecessary? If your amplifier has good spring reverb, it may be entirely sufficient for traditional styles. External reverb pedals offer more control and variety of reverb types — particularly hall, plate, and shimmer modes that amp spring reverb cannot provide. For complex needs, a pedal adds value. For simple spring reverb use, the amp's reverb is often excellent.
What is the best reverb setting for solo guitar? Hall reverb at 25–40% mix with medium-to-long decay (3–5 seconds) and 15–20ms pre-delay. This gives notes space to breathe and sustain into the reverb tail without washing out definition. Adjust mix downward if consecutive notes blur.
Should reverb come before or after delay? Reverb after delay is standard. Delay before reverb means the delay's repeats are each individually reverbed, creating a lush, expanding sound. Reverb before delay means the reverb tail gets delayed, which produces a less natural but sometimes interesting textural effect. Both are valid creatively, but delay-into-reverb is the standard order.
How do I stop reverb from making my guitar sound muddy? Three adjustments: reduce the mix (less reverb in the signal), shorten the decay (reverb tail fades faster), or add pre-delay (10–20ms keeps the attack clear). If these adjustments still sound muddy, consider whether the reverb type suits your amp's EQ — brighter amps with bright reverb can clash; try a darker reverb type.
Can I use reverb for rhythm guitar? Yes, but use it conservatively. Room reverb at 15–20% mix with short decay adds air to rhythm parts without washing them out. Hall or shimmer at high mix settings makes rhythm playing indistinct — reserve those for lead passages.
