Maestro Mariner Tremolo Pedal

The Maestro Mariner Tremolo pedal delivers lush, amp-like tremolo in a compact, easy-to-use stompbox. With two distinct modes on tap, it gives you everything from classic, smooth volume swells to rich, harmonic movement inspired by sought-after vintage amplifiers, all with intuitive controls that keep you focused on playing rather than menu diving.

At its heart, the Mariner Tremolo is all-analogue, offering a warm, organic feel that sits naturally in any rig. The simple three-knob layout makes it quick to dial in, while the Harmonic/Classic mode toggle effectively gives you two pedals in one. Whether you are after subtle movement to add life to clean chords or choppy, square-wave pulses that cut through a dense mix, this pedal has the range to cover it.

Designed with live performance in mind, the Mariner Tremolo features true bypass switching to keep your core tone intact when the effect is off. When engaged, the iconic Maestro logo lights up in red, yellow and blue, so you can see at a glance that your tremolo is active, even on a dark stage. Power it with a standard 9V battery or a regulated 9V DC supply and drop it straight onto your board.

From classic surf and vintage blues textures to cinematic soundscapes and modern rhythmic stutters, the Maestro Mariner Tremolo is a versatile, inspiring tool for players who want authentic amp-style tremolo with simple, stage-ready control.

Classic Mode Tremolo

In Classic mode, the Mariner Tremolo delivers traditional amplitude modulation that feels like a great valve amp pushed just right. You can move from gentle, breathing movement that adds depth to clean passages, through to sharper, more percussive pulses that help riffs and lead lines stand out in the mix.

Harmonic Mode Texture

Harmonic mode unlocks rich, textural tremolo tones reminiscent of a select few legendary vintage amplifiers. This mode adds a swirling, almost phaser-like quality to your sound, perfect for atmospheric parts, ambient swells and expressive lead work that needs extra character without overpowering your core tone.

Intuitive Three-Knob Control

The straightforward Depth, Shape and Speed controls make it easy to dial in exactly what you need. Depth sets how intense the tremolo feels, Shape morphs the waveform from smooth triangle to hard-edged square, and Speed sets the rate of the effect, from slow, rolling waves to fast, choppy tremolo for more rhythmic playing.

True Bypass with Visual Feedback

A true bypass footswitch keeps your dry signal pure when the pedal is off, preserving your tone across the rest of your signal chain. When you engage the effect, the bugles in the Maestro logo light up in red, yellow and blue, giving you clear visual confirmation that your tremolo is active at all times.

• Two Amp-Like Tremolo Modes - Switch between Classic and Harmonic modes for everything from smooth, traditional tremolo to rich, vintage-inspired harmonic textures. This effectively gives you two distinct tremolo flavours in a single pedal, expanding your tonal palette without taking up extra pedalboard space.
• Shape Control for Flexible Waveforms - The Shape control lets you continuously sweep from a rounded triangle wave to a hard-edged square wave. This makes it easy to fine-tune the feel of the tremolo, from subtle and musical to bold and choppy, so it can suit different songs, styles and playing dynamics.
• All-Analogue Signal Path - With all-analogue signal processing, the Mariner Tremolo delivers warm, organic modulation that integrates naturally with your guitar and amplifier. The result is a musical, responsive tremolo effect that feels inspiring under the fingers and works equally well with clean or driven tones.
• True Bypass and Illuminated Logo - True bypass switching ensures your tone remains unaffected when the pedal is off, while the illuminated Maestro logo provides instant visual feedback when the effect is engaged. This combination keeps your sound clean and your stage setup clear and easy to manage.
