KARTAKOU WARMER | HANDMADE OVERDRIVE / BLACK BASE

Warmer Overdrive captures the spirit of the Screamer while enriching it with both familiar features and unique solutions that push the pedal to the forefront of overdrives.

Touch-sensitive Gain knob paired with a clipping type switch lets you dial in anything from subtle, barely-there grit to a crunchy tone that cuts through exactly when you need it.

The built-in voltage multiplier doubles the incoming 9V to feed the main chip with 18 volts, significantly expanding dynamics and removing limitations caused by weak chip power.

Warmer also gives you:

• Full clipping bypass to use the pedal as a clean booster
• Hot-swappable main chip — choose from 5 options including the classic JRC4558
• Switchable bypass type: true bypass or J-FET buffered
• LED kill switch for ninja stealth mode

The pedal requires 9V DC power supply, center negative.

Base and LED colors can be customized. I can also print your graphics (logo, artwork, etc.) directly on the pedal for a little extra.
