Electro Harmonix 2020 Tuner V2

The Electro-Harmonix 2020 Tuner V2 is a compact chromatic pedal tuner designed to provide accurate, clearly visible tuning without occupying unnecessary pedalboard space.

Its bright display is easy to read during rehearsals, recording sessions and live performances, while ±1-cent accuracy provides the precision needed for dependable instrument setup and tuning. The wide B0 to B7 detection range makes it suitable for guitar, bass and other compatible amplified instruments.

A selectable bypass system allows the 2020 Tuner V2 to operate with either passive true bypass or buffered bypass. This gives players the freedom to preserve a completely passive signal path or use the built-in buffer to help maintain clarity through longer cables and larger pedalboards.

Engaging the tuner automatically mutes the audio output, allowing silent tuning between songs. Adjustable pitch calibration and three flat-tuning settings add further flexibility for alternative tunings and different musical environments.

Quick Product Summary

The Electro-Harmonix 2020 Tuner V2 is an ultra-compact chromatic pedal tuner with a high-visibility display, silent tuning and selectable true or buffered bypass.

It offers a broad B0–B7 tuning range, ±1-cent accuracy and adjustable reference pitch from 436Hz to 445Hz. Three flat-tuning modes make it easy to tune instruments down by a semitone, whole tone or one and a half tones without changing the displayed note names.

Its small footprint makes it an excellent choice for crowded pedalboards, compact rigs and players who need a straightforward tuner that remains easy to see on stage.

Why Choose the Electro-Harmonix 2020 Tuner V2?

Accurate ±1-Cent Tuning

The 2020 Tuner V2 provides tuning accuracy within one cent, making it suitable for everyday playing, live performance, rehearsals and recording.

Accurate tuning is particularly important when:

• Recording layered instrument parts

• Playing with keyboards or fixed-pitch instruments

• Setting intonation

• Using open chords

• Performing with multiple guitarists

• Moving between standard and alternative tunings

The clear tuning guide shows whether the note is flat, sharp or correctly centred.

Wide B0–B7 Detection Range

Its chromatic detection range extends from B0 to B7, covering the frequencies required for guitar, bass and a wide range of compatible amplified instruments.

Because the tuner is chromatic, it identifies all 12 notes rather than restricting the player to standard guitar tuning.

This makes it suitable for:

• Standard guitar tuning

• Extended-range guitar

• Four, five and six-string bass

• Drop tunings

• Open tunings

• Baritone guitar

• Capo-based tuning

• Compatible acoustic instruments fitted with pickups

High-Visibility Display

The bright display is designed to remain easy to read on a pedalboard.

A clear note indicator identifies the detected pitch, while the tuning guide shows whether the instrument needs to be adjusted upwards or downwards.

This is especially useful on dimly lit stages, where small or low-contrast displays can be difficult to read quickly.

Silent On-Stage Tuning

Pressing the footswitch engages the tuner and mutes the pedal’s audio output.

This allows players to tune silently between songs without sending tuning noises through the amplifier or PA system.

Press the footswitch again to return to the normal signal path.

Selectable True or Buffered Bypass

A side-mounted switch allows the player to choose between passive true bypass and buffered bypass.

Passive True Bypass

This mode creates a passive signal path when the tuner is disengaged.

It is ideal for:

• Smaller pedalboards

• Short cable runs

• Players who prefer true-bypass switching

• Rigs already containing a dedicated buffer

Buffered Bypass

Buffered mode maintains an active signal buffer when the tuner is disengaged.

This can help preserve high-frequency clarity when using:

• Long instrument cables

• Large pedalboards

• Several true-bypass pedals

• Complex stage setups

• Long cable runs between the pedalboard and amplifier

The selectable design allows the tuner to adapt to the needs of different rigs rather than committing the player to one bypass type.

Adjustable Reference Pitch

The Pitch button allows the tuner’s reference frequency to be adjusted from 436Hz to 445Hz in one-hertz steps.

The standard reference is A4 at 440Hz, but adjustable calibration can be useful when:

• Playing with an acoustic piano tuned away from A440

• Matching vintage recordings

• Performing with orchestral instruments

• Working with regional or ensemble-specific tuning standards

• Reproducing deliberately raised or lowered concert pitch

The tuner returns to 440Hz when powered up.

Three Flat-Tuning Modes

The Flat button cycles between normal tuning and three lowered tuning modes:

• Half a step down

• One whole step down

• One and a half steps down

These modes allow players to tune below standard pitch while continuing to use familiar note names on the display.

For example, a guitarist tuning every string down by a semitone can select the half-step-flat setting and tune using the standard E, A, D, G, B and E note references.

Ultra-Compact Pedalboard Footprint

The 2020 Tuner V2 measures just 46mm wide, allowing it to fit into spaces that would be too narrow for a conventional effects pedal.

Its compact size is particularly useful for:

• Crowded pedalboards

• Fly rigs

• Mini pedalboards

• Backup setups

• Acoustic pedalboards

• Bass rigs

• Portable recording systems

Although small, the chassis retains a full footswitch and a clearly visible display.

Straightforward Operation

The tuner avoids unnecessary menus and complicated programming.

Its controls consist of:

• Main bypass and tuner footswitch

• Pitch calibration button

• Flat-tuning button

• Buffer on/off switch

This makes it easy to operate during performance and quick to configure for different instruments or tunings.

Why Choose a Pedal Tuner?

A pedal tuner becomes a permanent part of the instrument signal chain, making it immediately accessible during rehearsals and performances.

Compared with a clip-on tuner, a pedal tuner reads the direct electrical signal from the instrument. This helps prevent surrounding stage noise from interfering with tuning detection.

Pedal tuners also provide practical performance benefits:

• Silent tuning through output muting

• Easy foot-operated activation

• Clear visibility on the floor

• No need to attach anything to the instrument

• Reliable operation in noisy venues

• Permanent integration into the pedalboard

• Convenient signal checking at the start of the effects chain

A tuner is normally placed first or close to the beginning of the pedal chain so it receives a clean and unprocessed instrument signal.

Who Is the Electro-Harmonix 2020 Tuner V2 For?

Performing Guitarists

The muted output and visible display make it easy to tune silently between songs.

Bassists

Its wide detection range accommodates standard and extended-range bass instruments.

Players with Compact Pedalboards

The narrow enclosure preserves space for additional effects without sacrificing a permanently connected tuner.

Musicians Using Lower Tunings

Three flat-tuning settings simplify tuning instruments down by up to one and a half tones.

Players with Large Pedalboards

Selectable buffered bypass can help maintain signal clarity through longer cables and several effects.

True-Bypass Users

The passive bypass setting allows the tuner circuit to be removed from the active signal path when disengaged.

Recording Musicians

Accurate tuning is essential when tracking doubled parts, layered arrangements and instruments alongside fixed-pitch sources.

Multi-Instrumentalists

Chromatic operation allows the tuner to detect any note within its range rather than being limited to standard guitar tuning.

Instrument → Tuner → Wah or Filter → Compression → Gain Pedals → Modulation → Delay → Reverb → Amplifier

Placing the tuner first also allows its selectable buffer to support the remaining pedalboard and cable run.

Electro-Harmonix 2020 Tuner V2 Compared with Other Tuners

Compared with the Original EHX-2020 Tuner

The original model provided compact chromatic tuning with true-bypass operation.

The V2 adds selectable passive or buffered bypass, allowing it to work more effectively across both simple and complex pedalboards.

Compared with a Clip-On Tuner

A clip-on tuner detects vibration through the instrument’s headstock or body. It is highly portable but may be affected by strong vibrations from other instruments on stage.

The 2020 Tuner V2 receives a direct electrical signal, provides silent output muting and remains permanently available on the pedalboard.

Compared with a Full-Size Pedal Tuner

A larger tuner may offer a wider display or additional tuning modes, but it occupies more pedalboard space.

The 2020 Tuner V2 provides the essential functions needed for most live and studio applications within an ultra-compact enclosure.

Compared with a Tuner Built into a Multi-Effects Unit

An integrated tuner can be convenient, but access may require navigating menus or holding multiple switches.

The 2020 Tuner V2 provides a dedicated footswitch and remains independent from the settings or operating mode of other equipment.

Compared with a True-Bypass-Only Tuner

A true-bypass-only tuner removes its active electronics from the signal chain when disengaged.

The 2020 Tuner V2 can do the same, but it also offers buffered operation when extra signal support is required.
