The Exact John Mayer Klon Settings: Unlocking The 11-11-1 Secret To His Transparent Overdrive Tone

Contents

For guitarists obsessed with John Mayer's dynamic, glassy, and articulate overdrive tone, the Klon Centaur is the undisputed holy grail pedal at the heart of his rig. As of late 2024, the quest for his *exact* settings has been answered by a direct interaction with the man himself, confirming the specific, low-gain approach that allows the legendary pedal to function more as a preamp and clean boost, rather than a traditional distortion unit. This article dives deep into the confirmed settings, the technical rationale, and how to replicate the "transparent overdrive" foundation that underpins Mayer’s most iconic sounds.

The Klon Centaur, or its modern iteration the Klon KTR, is not used by Mayer for heavy distortion, but rather as a foundational tone-shaping tool. It adds harmonic richness, a subtle mid-range push, and a signature high-end sparkle that is essential to his sound, especially when playing through high-headroom amplifiers like his Dumble or Two-Rock models. Understanding these settings is the first step in achieving that highly sought-after, responsive, and dynamic tone.

The Confirmed John Mayer Klon Centaur Settings: The 11-11-1 Rule

The most reliable and specific confirmation of John Mayer's go-to Klon Centaur settings came from a fan interaction where the guitarist personally marked his preferred settings on the fan's pedal. This direct evidence cuts through years of speculation and provides a definitive starting point for tone-chasers.

  • Gain (Drive): 11 o'clock
  • Output (Volume): 11 o'clock
  • Treble: 1 o'clock (sometimes cited as 12 o'clock, depending on the venue/amp)

This configuration is critical because it reveals Mayer’s primary use for the Klon: a low-gain, high-headroom boost.

Why the 11-11-1 Setting is John Mayer's Secret Weapon

The placement of each knob is intentional and serves a specific purpose in Mayer's complex signal chain:

1. Low Gain (11 O'Clock) - The Transparent Boost

Setting the gain knob to just 11 o'clock keeps the pedal firmly in "clean boost" territory. The Klon Centaur is famous for its unique clipping circuit, which blends the clean signal with a buffered, slightly overdriven signal. By keeping the gain low, Mayer utilizes the pedal's unique ability to add a subtle, three-dimensional harmonic complexity without introducing significant fuzz or distortion. This ensures the natural tone of his guitar (like the Fender Stratocaster or PRS Silver Sky) and amplifier remains dominant.

2. Unity/Slightly Boosted Output (11 O'Clock) - Pushing the Front End

The output is set to 11 o'clock, which is often near unity gain (the same volume as the bypass signal) or just slightly above. This setting allows the Klon to function like a mild preamp, subtly pushing the front end of his already clean, high-headroom amplifiers (Dumble, Two-Rock). This gentle push maximizes the amp's dynamic response, making the guitar feel more alive and reactive to his picking attack.

3. Treble Boost (1 O'Clock) - The Glassy Top End

The treble control is arguably the most crucial knob in this setting. Set to 1 o'clock, it provides a noticeable but not harsh high-frequency boost. This is the source of the "glassy," "chimey," and articulate top-end that defines Mayer’s clean and edge-of-breakup tones. This treble boost compensates for any high-end loss in the signal chain and ensures his notes cut through the mix with clarity and punch, especially when playing complex chords or fingerstyle passages.

Klon Stacking: The Dual-Overdrive Strategy

While the Klon Centaur provides the foundational transparent overdrive, John Mayer rarely uses it alone for his full lead tone. His signature sound relies heavily on a "stacking" strategy, combining the Klon with another legendary overdrive pedal: the Ibanez Tube Screamer TS10.

The Klon + TS10 Combination

This dual-overdrive setup is a masterclass in tone shaping. The Klon (set to 11-11-1) acts as the first stage—a transparent, full-range boost—feeding into the Tube Screamer.

  • Klon Centaur (Transparent Overdrive): Provides the initial boost, harmonic richness, and high-end clarity.
  • Ibanez Tube Screamer TS10 (Mid-Hump Overdrive): The Tube Screamer, set with the classic "Mayer settings" (Level high, Tone low, Drive low-to-mid), introduces a focused mid-range hump.

When stacked, the Klon pushes the Tube Screamer, resulting in a fatter, more compressed, and vocal-like lead tone that retains the clarity of the Klon while gaining the powerful mid-range presence of the TS10. This is the sound you hear on tracks like "Gravity" and "Slow Dancing in a Burning Room."

The Klon KTR and Clone Alternative Settings

Given the scarcity and astronomical price of the original '90s Klon Centaur, most guitarists—including Mayer himself on some occasions—rely on a Klon KTR or high-quality clones (often called "klones"). The good news is that the 11-11-1 rule applies universally.

Replicating the Tone with Klon Clones

The Klon Centaur's circuit is complex, but the core function is a transparent overdrive/boost. When using a Klon KTR or a popular klone like the Wampler Tumnus, J Rockett Archer, or Ryra The Klone, you should start with the 11-11-1 settings and then fine-tune based on your amplifier:

  • If your amp is dark: Nudge the Treble knob slightly past 1 o’clock (up to 2 o’clock).
  • If your amp is already bright: Roll the Treble back to 12 o’clock (noon).
  • For more sustain: Increase the Output knob to 1 o’clock to push the amp harder.

Remember that the Klon’s effect is highly dependent on the amplifier. Mayer’s use of high-end, clean platforms like Dumble Overdrive Special and Two-Rock Studio Pro amps ensures the Klon’s transparency shines through. If you are using a mid-gain amp, you may need to reduce the Klon's Gain even further to maintain clarity.

Beyond the Knobs: Other Essential John Mayer Tone Entities

While the Klon settings are vital, achieving the complete John Mayer sound requires a holistic approach that includes other key elements:

  1. The Amp Platform: High-headroom, clean amps are non-negotiable. Dumble, Two-Rock, and Fender Bandmaster-style circuits are the foundation, providing a pristine canvas for the Klon’s subtle coloration.
  2. The Guitar: Fender Stratocaster, PRS Silver Sky, and the custom-built PRS Super Eagle all contribute to the fundamental clean tone before the pedals.
  3. The Stacking Partner: The Ibanez TS10 or a Bluesbreaker-style pedal (like the Analog Man King of Tone or JHS Morning Glory) is necessary for the second stage of gain.
  4. The Buffer: The Klon Centaur itself features a high-quality buffer circuit that is always active, even when the effect is bypassed. This buffer is crucial for maintaining signal integrity across Mayer's large pedalboard.
  5. Other Overdrives: Mayer is constantly experimenting, having also incorporated pedals like the Shins Music Dumbloid B and the Blackstone Appliances Mosfet Overdrive into his rig over the years.

In summary, the 11-11-1 setting on the Klon Centaur is the definitive starting point for anyone seeking John Mayer's signature transparent overdrive. It’s a testament to the fact that the Klon is used not for raw distortion, but as an essential tone-sweetener and clean boost, unlocking the true potential of his exceptional amplifier and guitar combination.
