maestro 2

The Maestro Mariner Tremolo belongs to the second batch of pedals released by Gibson under the line named after the venerable Maestro brand, makers of some of the very early vintage stompboxes.

Like the other pedals in the line, the Mariner is a pretty straightforward device featuring three knobs and one toggle switch, which delivers two slightly different voicings:

Classic: That’s the Fender amp-style tremolo (aka BIAS) that we all know and love.

Harmonic: a more complex and lush type of tremolo that modulates high and low frequencies separately, adding some extra frequency fluctuations due to phasing.

Besides the classic Depth and Speed knobs, it features an intriguing Shape control that takes the modulation’s LFO from a triangle to a square and anything in between. With that knob all the way to the right, the effect will be extremely choppy, causing the sound to be intermittent.

Maestro Mariner Tremolo, Builder’s Notes

Two Tremolo Pedals in One
The Maestro Mariner Tremolo offers two amp-like tremolo options for “two pedals in one” functionality and increased sonic versatility. In Classic mode, you can swing from subtle, smooth amplitude modulation all the way to a sharper-edged, biting modulation, with many creative areas to explore in-between. In Harmonic mode, you can dial up timeless textural Harmonic Tremolo tones that are very reminiscent of the tones produced by a select few vintage amplifier tremolos. With its amp-like tones and ability to vary the tremolo’s wave shape, the Mariner Tremolo delivers a wide range of inspiring possibilities. The intuitive 3-knob control layout lets users quickly set the desired Depth (the intensity of the tremolo effect), control the Shape of the waveform (from a triangle wave to a square wave), and adjust the Speed of the tremolo effect. The true bypass footswitch triggers the LED lights in the bugles in the Maestro logo when it’s on, so you’ll always know when the effect is active.
