The Warmer by Kartakou Amplification is a versatile overdrive pedal designed to deliver creamy overdrive tones with a wide range of variations and possibilities. It is suitable for a diverse range of guitarists, from beginners to professionals, and can be used in studio recording or live performances.
Key Features:
- Overdrive / Boost Modes: The Warmer can be configured to operate as a boost
pedal with adjustable Gain, Tone, and Volume controls. The left switch
activates the boost mode.
- Voltage Upgrade: The internal voltage pump doubles the standard 9 Volts
pedal power to 18 Volts, providing a bipolar supply for the main chip to
maximize its dynamic potential.
- Swapable OPamp Design: The pedal comes with five different Op Amps,
allowing users to customize the pedal's tone by swapping the main chip. This
feature enables users to experiment with different tones and noise levels.
- Lows Revival: The pedal includes a feature to bring back certain low
frequencies that may be cropped by a gain stage, allowing users to establish a
focused overdrive tone.
- Soft / Rough Clipping: The Warmer offers two overdrive styles, with the
option to activate rough limiting. This feature is available only in overdrive
mode.
- Passive / Buffered Bypass: Users can choose between passive bypass for
minimalistic setups or J-Fet bypass to preserve overtones, especially when
using active pickups.
- Illuminated Design: The pedal features an engaging lighting effect when the
effect is activated, adding a visually appealing element to the pedalboard.
Controls:
- Gain: Sets the amount of overdrive.
- Tone: Adjusts the tone of the pedal.
- Volume: Controls the output volume.
- Face Switches: Enable selection of Boost or Overdrive modes, clipping
styles, and low-frequency comeback.

or active J-Fet bypass mode.
