Analog Envelope Filter for Guitar & Bass

The BFKK Cry-Bot is a 100 percent analog envelope filter pedal that responds directly to picking dynamics. It is designed for both guitar and bass, delivering fast and accurate tracking across the instrument's range. A true bypass footswitch keeps the signal path clean when the effect is disengaged. This pedal suits players seeking expressive, touch-sensitive wah tones without digital processing.

Four Knobs Shape the Funky Range

Wide tone shaping is handled by four control knobs that adjust the filter response to taste. The circuit requires a standard 9V centre negative power supply, which is not included with the pedal. No battery compartment is mentioned in the specifications. Players should verify their power supply matches the centre negative polarity before use.

Upgrade from Fixed Wah or Basic Filters

This pedal replaces a fixed wah pedal or a simpler auto wah with a single knob, adding dynamic sensitivity and broader tonal control. The jump is worth it when the music demands filter sweeps that follow every pick attack rather than a preset sweep. It is not for players who need preset storage, MIDI control or a built-in expression pedal input.

Questions about this item

Which envelope-filter pedal should I choose if I need analog tracking for both guitar and bass?

This pedal uses a 100 % analog circuit that responds to picking dynamics and tracks accurately on both guitar and bass, so a single unit covers both instruments.

What does the 100 % analog envelope-filter design mean when I play through an amp?

The circuit reacts directly to your attack without digital conversion, giving an immediate, touch-sensitive wah sweep that follows every note.

How does the true-bypass footswitch affect the signal when the effect is off?

True bypass routes the instrument straight to the amp with no buffering, keeping the original tone completely clean when the pedal is disengaged.
