WORKING CONDITION: Excellent. This Keeley mod adds several welcomed improvements to the stock MT-2. The gain is nearly unlimited and amp-like, and the sweepable midrange creates a newfound ability to really dial in the pedal for stage and studio.

PHYSICAL CONDITION: Excellent. This is a really clean pedal, and the mods were very tastefully done. Excellent example with no physical issues.

MODEL: MT-2 Metal Zone w/ Keeley "Twilight" Modification

PRODUCT DESCRIPTION: This listing is for a Boss MT-2 Metal Zone Effects Pedal w/ Keeley "Twilight" Modification from the touring arsenal of Maroon 5.

SPECS:

• Serial # N/A
• The Keeley mod for the Boss MT-2 Metal Zone pedal, known as the "Twilight Mod", significantly enhances the pedal's versatility, clarity, and tonal range by replacing key components and adding a three-way toggle switch.
• Three-Way Diode Switch: This is the core feature of the mod, offering versatile distortion characteristics:
  • Standard Mode: Retains a sound similar to the original MT-2 but with less noise and improved EQ.
  • Tri-Diode (or Ultra) Mode: Increases dynamic range and pick sensitivity with enhanced bass response and saturation.
  • Ultra Tube (or Right switch position) Mode: Designed to emulate the natural, smooth sound of a tube amplifier, often compared to Marshall JCM800 or Mesa Boogie tones, and is suited for 4x12 cabinets.
• Component Upgrades: The mod involves upgrading internal components to enhance sound quality and durability:
  • Metal film resistors and poly capacitors are used to reduce noise and improve midrange and high-frequency transparency.
  • High-quality diodes are installed for the different clipping options.
• Enhanced EQ Response: The modifications improve the functionality of the pedal's powerful semi-parametric EQ, making it more usable and less "nasally" or "papery" than the stock version.
• Aesthetics: A bright blue LED replaces the stock red one.
• Versatility: The mod transforms the pedal from a one-dimensional, divisive unit into a more refined, versatile, and studio-quality distortion pedal suitable for various genres beyond just metal
