Description

Introducing the Keeley Katana Mini, an embodiment of exquisite tonal amplification in a compact package. This meticulously crafted device is designed to elevate your sound without compromising its inherent qualities. Offering an impressive mirror reflection of your tone, it's louder, richer, and harmonically satisfying. Pull out on the volume knob to explore the realms of overdriven tone. The Mini Katana is versatile enough to be left on continuously, working to push your amp to its limits, or used sporadically to cut through the mix with precision.

The Mini Katana is more than just a clean boost. It's a 4 Mode Booster, equipped with dual micro switches that unlock four distinct sounds. Whether you crave a high-gain overdrive or a warmer, softer tone, the Mini Katana has you covered. Engage both switches simultaneously, and you're treated to a thick, creamy, tube-amp-inspired boost with ample volume on tap.

The Katana lineage dates back to 2002, marking the genesis of boutique clean boost in the music industry. The Mini Katana continues this legacy, employing cascading FET stages for that unmistakable tube-amp emulation.

Key Features:

  • Booster effect pedal with over 35dB of boost
  • True bypass for preserving signal integrity when not in use
  • Powered exclusively via a 9V AC/DC mains adapter (not included)
  • Hand-built in the USA for assured quality and reliability
  • Four distinct sound modes unlocked via dual micro switches
  • Capable of creating warm, overdriven tones and clean, amplified sounds
  • Based on the original dual class A JFET design of the 2002 Katana
  • Cascading FET stages mimic the rich, harmonic tones of tube amps

Use cases and applications

  • The Keeley Katana is effectively used by John Mayer to boost low-output pickups, especially in a Fender Strat, providing a significant volume lift for solos.

    Source
  • A common pedal chain setup involves placing the Tube Screamer first, followed by the Angry Charlie, with the Katana last to maximize solo boost potential.

This is a photo that I took with my iPhone of Guy Chadwick’s pedalboard, and the Robert Keeley Katana Mini can be seen at the back of the board. It was difficult to get a good photo of the whole board from the ground ad the stage was higher up, but as an eyewitness, I can confirm that it was definitely a Keeley Katana Mini.
