Death By Audio Crossover Fuzz

A Death By Audio fuzz designed as a studio crossover... but in chaos mode

With the Crossover Fuzz, Death By Audio pushes the fuzz concept far beyond simple "more gain." The idea is that of a crossover (as in pro audio): lows and highs are separated, then each is treated differently. The result: you can keep thick, solid bass while letting the highs bite and sizzle without everything turning into mush. And since DBA loves extreme textures, the resonant filter section can become a true instrument on its own, capable of very controlled sounds... or intentionally wild, unpredictable behaviors that are pure joy.

Who it's for and what it's for: from massive riffs to sound design, in studio and on stage

This pedal is aimed at guitarists, bassists, and tinkerers who want to sculpt their fuzz rather than endure it. In rock, stoner, noise, garage, post-rock, experimental metal, or electro-inspired guitar, the band separation allows you to keep the impact of the lows while working an aggressive presence in the upper spectrum. Live, it shines if you play through two amps (or a stereo rig): lows on one side, highs on the other, for a huge and clear image. In the studio, it's a sound design weapon: automation via expression/CV, filtered fuzz layers, and shifting textures that sit in the mix without complex EQ.

Controls, routing, and details that make all the difference

The Crossover Fuzz splits your signal into two paths: LOWS (low-pass) and HIGHS (high-pass). The FREQ knob sets the crossover point: the more you turn it, the more you rebalance the share of lows and highs, with an immediate effect on the sense of "size" and attack. The RES control affects the resonance of both filters: smooth and musical for subtle "wah" curves, or extremely sharp to create frequency peaks, up to self-oscillation. Each band has its own GAIN (from clean to overdrive then fuzz) and VOL (output level), allowing you to compensate, boost one band, or conversely scoop a spectral area.

To go further, the FREQ EXP input allows external control of the crossover via expression pedal or 0-5V CV. This is where the pedal becomes "alive": synchronized sweeps, transitions between massive and cutting sounds, stereo movements if you use the separate outputs... Finally, an internal Light selector lets you change the LED colors (two color sets), handy for stage visibility and pedalboard aesthetics.

On the I/O side, the pedal offers configurations designed for experimentation: in mono (H or L input) you get a mixed signal on the HIGHS MONO output. In mono to stereo, you send lows to LOWS and highs to HIGHS (perfect for two amps or two effects chains). In stereo to mono, you can sum two sources into one output. And in full stereo, each input routes to its dedicated output for total separation.

Sound

Expect a dense, snappy, and highly textured fuzz, with a real sense of depth thanks to the separate band processing. The lows can stay full and authoritative (ideal for heavy riffs or bass), while the highs bring grain, bite, and a "torn" edge. The filter resonance adds an expressive dimension: at moderate settings, you get precise shaping that helps you "sit" in the mix; pushing RES, the pedal can generate aggressive peaks, quasi-synth sounds, and reactions that reward dynamic playing and real-time tweaks. Used in split mode, it can give the impression of a wider sound than a classic fuzz, with a spectacular stereo image and a decidedly modern character, all while remaining analog.
