JHS 3 Series PHERB Lo-Fi Reverb Pedal

The JHS 3 Series PHERB is what happens when a dark, lo-fi reverb collides with a chewy four-stage phaser and refuses to behave. Designed in a frantic 35 hour burst of inspiration, this compact stompbox gives you swirling ambience, pulsing drones and broken, bitcrushed chaos at the flick of a switch. It is not a polite room reverb or a subtle modulation pedal; PHERB is built for players who want their ambience to be part of the riff, not an effect sprinkled on top.

At its core, PHERB runs a moody reverb straight into a vintage-style phase shifter, then blends the result back in with your dry guitar. There is no option to separate them, no series or parallel choices and no blend control for the individual effects. Instead, you get three intuitive knobs that always do something musical, from barely there movement to seasick sweeps and cavernous tails that pulse under your playing like a synth pad.

Flip into BREAK mode, and PHERB becomes something entirely different. Your guitar hits an asymmetric bitcrusher-style circuit with analogue-style clipping before it even touches the reverb or phaser, turning chords into crumbling fuzz and single notes into mangled, industrial textures. Short decay times give you a snarling, broken fuzz voice, while long lengths create nightmarish, collapsing soundscapes that still sit inspiringly under your playing.

Whether you are building shoegaze walls of sound, industrial noise, experimental pop textures or ambient beds where the reverb is the foundation of the mix, PHERB rewards players who like to experiment. Put it near the end of your chain, twist the Mix, Speed and Length controls and you will quickly find everything from subtle movement to full-on sonic destruction, all in a simple, affordable 3 Series enclosure.

Phaser and Reverb, Locked Together

PHERB is a purpose-built combination of dark, lo-fi reverb running into a four-stage phase shifter, always on together. This fixed architecture means you are not menu diving or juggling routing options; you simply plug in and immediately get the swirling, chorused ambience that inspired the design. It is the sound of a phaser living inside the reverb, not sitting politely next to it.

Dark, Lo Fi Reverb with Massive Range

The reverb engine is intentionally murky, chorused and characterful, with a decay range from a tight 241 ms up to almost 50 seconds. At shorter settings, it adds the feel of a lively, slightly warped room, while long Length settings create pulsing drones that breathe under your playing like a pad. It is perfect for players who want ambience with attitude rather than pristine studio realism.

Vintage Style Four Stage Phaser

Inspired by classic four-stage phasers, the modulation in PHERB delivers the familiar swish without swallowing your tone. The notch sweeps are shifted up the frequency spectrum to stay clear of the reverb’s low mids, so your sound remains present even at deeper settings. With a Speed range from 0.05 Hz to 5 Hz, you can move from barely there motion to full seasick wobble.

BREAK Mode for Bitcrushed Destruction

Engage the BREAK toggle and your dry signal hits an asymmetric bitcrusher-style circuit with analogue like clipping before it feeds the reverb and phaser. This turns PHERB into a snarling, glitchy fuzz and ambience machine, ideal for riffs that need to sound broken, industrial textures and experimental sound design. In BREAK mode the phaser is always active, so the destruction stays animated and alive.

• Phaser Plus Reverb in One Box - PHERB combines a dark, lo fi reverb with a four stage phaser, with both effects always on and interacting. This gives you a unique, swirling ambience that feels like a single instrument rather than two separate pedals, ideal for players who want to build signature textures quickly.
• Expressive, Wide Ranging Controls - With just Mix, Speed and Length, every knob turn produces a usable sound. You can dial in subtle movement, pulsing drones or cavernous washes without getting lost in complex parameters, making PHERB quick to set on stage and endlessly tweakable in the studio.
• BREAK Mode for Aggressive Tones - The BREAK toggle routes your signal through a destructive bitcrusher style stage before the reverb and phaser, creating everything from spluttering fuzz to nightmarish, decaying soundscapes. It is perfect for shoegaze, industrial, noise and any style where the ambience should fight back.
• Compact 3 Series Format - Housed in the familiar JHS 3 Series enclosure with top mounted power and side mounted jacks, PHERB fits easily onto crowded pedalboards. Its simple layout and standard 9VDC operation mean you can drop it straight into your existing rig without rethinking your whole setup.
