The QF2 by Iron Ether is an innovative distortion pedal that divides the incoming signal into four distinct frequency bands, each of which is individually processed through its dedicated distortion module. The central frequencies of these four filters are adjustable, covering a sweeping range of three octaves. This intricate parallel processing generates novel sonic textures and enhances the playability of complex chords, ensuring a more refined, sustained sound with reduced harshness and heightened clarity.
Rooted in the legacy of Craig Anderton's original 1985 "Quadrafuzz" rack-mount effect, the QF2 has been completely reimagined, featuring augmented resonance controls for each channel and a comprehensive frequency control that simultaneously adjusts all four filters, imparting unique vocal-like characteristics. Additionally, the inclusion of an expression pedal input for this frequency control invites real-time dynamic manipulation.
The pedal is capable of producing a diverse array of tones, from subtle, low- gain overdrive to velvety smooth sustain, gritty distortion, defined crunchy fuzz, organic analog octave elevation, and distinctive synth and fuzz-wah effects. The standard QF2 Copper model is further enhanced with a Dry control, allowing for a seamless blend of the unaffected signal with the processed output, offering an expanded palette of tonal possibilities.
