Ultimate Klon Killer? The Keeley Manis Overdrive Demo

With switches that add germanium transistors and a bass boost to the classic Klon formula, Keeley delivers a more flexible and often more potent overdrive.


The Keeley Manis uniquely combines both germanium NOS transistors and diodes for more compression and saturation. This evolution is unlike any other mythical Klone! Keeley writes the next chapter in the legend of the mythical Klone pedal with several storied upgrades and features. First up is the germanium diode switch. The essential germanium diodes are at the heart of the myth. By transposing germanium diodes with germanium transistors (Cold War-era devices), we increase the sustain and saturation in the pedal. The Manis can give you a softer attack that sounds more like a tube amp. Less mid-forward, more tube-amp like. This feels incredible under your fingertips. Wouldn’t you like to hear a little more of the natural low end from your guitar? The bass boost switch pushes the lower half of the mid-focused response by one octave and increases the output by +3dB. It’s the perfect low end recovery for single coil guitars. You can choose True Bypass or Buffered Silent Switching on the fly. The Manis is built like a tank and is the first Klone you can power with 18 volts for increased headroom. The Manis is an evolution of the original circuit.

  • The Manis isn't just a mod: it’s an evolution of the mythical overdrive mid-boost pedal.
  • Ge-Trans Switch offers a welcome difference in feel of the circuit with more of a tube-like saturation and compression.
  • The Bass+ Switch – Lowers the frequency response by one octave and then pushes 3dB harder
  • True-Bypass or Silent Switching – Whichever works and sounds best in your rig
  • Power Protection up to 18 volts for increased headroom - without damaging the charge pump.

Germanium Transistors

Central to the superior tone from the Manis Overdrive is the germanium transistors we select for increased saturation, compression, and sustain. Each transistor is tested for noise and accuracy ensuring you have an incredible tone.

Switchable Low Frequency Cutoff

The Manis Overdrive gives you just the perfect lift in bass response so that your tone is not as mid-focused. Perfect for making single coils fatter, fuller, and more powerful.

Buffered Bypass or True Bypass

The Keeley Manis Overdrive allows you to quickly switch between either mode. Having a great buffer will make your rig sound strong and clear even when the pedal is off. Buffered switching prevents the pops and clicks of true-bypass switching. If you want to turn on true-bypass, simply press and hold the foot switch for two seconds. Holding the switch for two seconds toggle between modes. True Bypass is great if a buffer might affect the tone of a vintage pedal. Enjoy truly silent switching and a better sounding rig with Keeley’s buffered switching mode.
