Description

Spread the love

The ZVEX Sonar isn't your typical tremolo pedal. A dream for experimentalists, the scintillating Sonar can chop up practically any audio signal fed through it to create warped, idiosyncratic sounds that'll add intrigue to any music you make with it!

Designed for Distorted Tones

One of the most unique aspects of ZVEX's Sonar is its ability to cut down a high-gain signal to silence. This is unlike most other tremolo pedals on the market, which are designed for use with clean tones and therefore unable to take a distorted sound "down to zero" – so to speak.

The ZVEX Sonar is different; engineered to be used in conjunction with high-gain amps and pedals. Chuck something like a ZVEX Fuzz Factory in front of it and you'll form chaotic, world-ending tones to scare any listener! However, the ZVEX Sonar can also sound gorgeously transparent like a traditional tremolo pedal, making it adaptable for all kinds of guitar textures and musical styles.

Fun Hidden Features

If you really like to manipulate your tones to create crazy effects and soundscapes, the ZVEX Sonar allows you to increase or decrease its tempo and affect its duty cycle (amount of time the trem is ON in a given cycle) on-the-fly – and even change both simultaneously!

The unit also has 'Tap Tempo' switch for synchronising the tremolo effect in time with accompaniment, and a slew of advanced hidden features ('Attack', 'Release' and 'Depth' controls). To access these parameters, you need to hold down the tap button for one second. Keep holding the tap button and the yellow LEDs should start slowly flashing. The 'Speed' knob is now 'Attack', the 'Duty' knob is 'Release', and the 'Delta' knob is now 'Depth'. The original parameters will not change unless you move the knobs.

Controls

Volume: Park this all the way clockwise for slightly over unity gain. If you need more gain (on either “clean” or “machine” modes), a trimmer is inside the pedal that can be pushed harder clockwise. This will break-up the “clean” signal though.
Speed: Manual control of tempo. 'Attack' (hidden function) controls how quickly audio reaches peak volume of tremolo.
Duty: Controls duration of peak audio, the “on” portion of tremolo. 'Release' (hidden function) affects how quickly audio ramps down from peak.
Delta: Controls the rate of change when unit is in “Arrow Up/Down Mode”. 'Depth' (hidden function) controls minimum volume of quiet portion of tremolo.

Switches

Bypass: Effect on/off.
Tap Tempo: Calculates tempo by taking the last two user taps. Always overrides a manually set tempo. The pedal will allow tempos as slow as 4 seconds per cycle. This switch also functions as a “shift key” to access 'Hidden Wave Shaping' functions.
Clean/Machine Mini Toggle Switch: “Clean” is a relatively clean sound based on our Super Hard On boost. “Machine” is our gnarly cross-over distortion circuit.
Tap Tempo Mini Toggle Switch: Allows user to set tempo to 2x or 4x original tap rate.
Arrow Up/Down: Controls the up or down direction of auto parameter change, also selects which parameters are being changed. Please refer to the back of this page for more detail on this function.

Distortion

Distortion pedals take your clean guitar signal and transform it into something bigger, bolder, and full of attitude. By clipping the waveform, they add sustain, bite, and aggression, creating that thick, compressed tone that’s powered rock music for decades. From the growling crunch of classic hard rock to the tight, saturated roar of modern metal, distortion is all about energy and presence. It gives every note weight and authority, pushing your amp to its limits and beyond.

There are countless flavours of distortion, each with its own texture and edge. Some sound smooth and creamy, others raw and gnarly like tearing fabric. It’s the sonic equivalent of turning up the heat until the sound cooks — rich, sizzling, and perfectly seasoned to taste. Whether used for rhythm muscle or soaring leads, a good distortion pedal doesn’t just add volume; it adds personality, grit, and that unmistakable sense of power under your fingers.

Fuzz

A fuzz pedal is one of the earliest and most aggressive forms of distortion, turning your clean guitar signal into a thick, saturated wall of sound. It works by clipping the waveform almost flat, creating a compressed, gritty tone full of harmonic overtones. The result is raw, unruly, and unmistakable — from the sputtering breakup of vintage germanium circuits to the searing sustain of modern silicon designs. Fuzz pedals react strongly to your guitar’s volume and pickup choice, making them dynamic tools for expressive players.

Whether you’re chasing the classic tones of Hendrix and the Smashing Pumpkins or exploring heavy, experimental textures, fuzz remains a favourite for its personality and unpredictability. It can sound smooth and sustaining, or wild and velcro-like, depending on how it’s set up. A good fuzz pedal cuts through the mix while adding thickness and attitude, turning any riff or lead line into something bold and unmistakably alive.

New

This is brand new, fresh in, and a UK warranty is included. New Gear always comes from trusted UK music retailers.

Tremolo

A tremolo pedal modulates the volume of your guitar signal up and down in a rhythmic pattern, creating a pulsing or wavering effect that can sound vintage and hypnotic or sharp and choppy depending on the settings. It’s one of the oldest effects in guitar history, famously used on classic amps from the 1950s and ’60s.

Most tremolo pedals let you control the speed, depth, and wave shape, allowing you to go from smooth, subtle swells to intense stuttering tones. It’s a simple but expressive effect that adds movement and character to your sound.

Volume

Volume pedals control the output level of a guitar signal using a foot-operated treadle. They allow smooth volume swells, dynamic control during playing, and easy muting between songs. Volume pedals can be placed at different points in the signal chain to either control overall loudness or adjust gain and drive behaviour when positioned before distortion or overdrive pedals.
