Description
Description
The Tone Tweaker is a 12dB boost pedal designed for guitarists seeking the perfect tone.
Conceived, designed and manufactured by a team of engineers with decades of experience developing Carl Martin pedals, this compact pedal lets you unlock the full potential of your favorite gear.
The internal clean boost circuit operates at high voltage, providing high headroom and a significant increase in volume.
The built-in 3-band EQ adds warmth to the midrange, sharpness to the highs, and depth to the lows, providing subtle yet powerful effects that can help guitar solos blend into the mix or add punch to rhythm playing.
