Fanmuzk Lady Rowland Bass Overdrive Pedal Drive Effect for Active/Passive Bass True Bypass

Sound & Feature Upgrades

Retains the original B3K’s iconic tone with a new Mid Boost (300Hz-1kHz 6dB) for enhanced mix cut-through.

Replaced attack switch with a Tone knob (3kHz-8kHz variable control) for precise high-harmonic adjustment covering warm tube-like overdrives to aggressive bass distortions.

Includes the classic Grunt switch for massive low-end boost thickening your sound for heavy styles.

Versatility & Ease of Use

Intuitive controls: Blend (clean/overdriven mix) Level (overdrive volume) Drive (saturation amount) for easy tone shaping.

Works flawlessly with both active and passive basses; supports 9V (standard) and 12V power (for extra headroom).

Controls

Blend: Mixes the clean input signal with the overdriven signal. The clean signal remains at unity gain while the volume of the overdriven signal is set by the Level knob allowing for fine control of the blend ratio.

Tone: Controls the high frequency content of the sound. A variable low pass filter from 3kHz (ccw) to 8kHz (cw).

Level: Sets the volume of the overdriven signal.

Drive: Sets the amount of saturation in the overdriven signal.

Grunt: When engaged provides a massive low end boost to really thicken your sound.

Mid Boost: Gives a subtle 6dB boost from 300 Hz to 1kHz to help you cut through a bit more.
