Meris Mercury 7

The Meris Mercury 7 reverb pedal is designed to send you into an eternal dream state with its wealth of stunning reverb algorithms.

It is inspired by Vangelis’ majestic soundtrack for the sci-fi masterpiece Blade Runner.

What does the Mercury 7 sound like?

Subtle plates and huge cathedrals to massive building soundscapes, swirling modulation, epic auto-swells, and shimmering pads.
Whether you’re looking to capture the sound and feel of well known earthly spaces, or that of huge starlit galaxies far away, the Mercury 7  delivers!
Meris has left no stone unturned in their journey to bring advanced studio reverb capabilities to your pedalboard.
The Mercury 7 takes everything from the highly regarded Mercury 7 500-series studio rack and distills it into a compact, intuitive pedal.

Ultraplate and Cathedral reverb algorithms

Mercury 7 delivers a superb range of ambient tones because it has two different reverb algorithms – Ultraplate and Cathedral.
Now, for instance, throw in the ability to modulate, pitch-shift, swell, sustain, and EQ the reverb in a million different ways!
You now have a reverb pedal that has your back!
Whether you’re going for smooth on-stage ambience or otherworldly sound designs. For instance, sounds that could easily form the backdrop to your favourite movie.
In addition, Mercury 7 holds one of the most impressive stereo reverb images ever made.
It also has the ability to morph between sounds because of its vast MIDI capabilities.
Mercury 7 is in essence way more than just another reverb pedal. It’s a deep and highly musical creative instrument in its own right.


Space Decay:

Sets decay energy of the reverberation space.

Alt Function: Predelay Sets the amount of time that elapses before the onset of reverberation


Sets overall modulation depth of the reverb algorithm.

Alt Function: Mod Speed Sets dominant modulation speed of the reverb algorithm


Adjusts Mix of Dry and Wet signals in analogue domain

Alt Function: Pitch Vector Mix Adjusts mix between intra-tank pitch-shifted reflections and normal reflections inside the reverb tank

Lo Frequency:

Changes how low frequencies react in the reverb algorithm.

When set closer to max, low-frequency decay times are extended giving the impression of a larger room.

Alt Function: Density Sets the amount of initial build-up of echoes before the reverb tank

Pitch Vector:

Sets intra tank pitch interval to Octave down, slight pitch up, slight pitch down, 5th up, or octave up.
Decay, Pitch Vector Mix & Hi/Lo Freq controls all interact to sculpt the intra-tank pitch regeneration.
Alt Function: Attack Time Sets the attack time for the swell envelope

Hi Frequency:

Changes how high frequencies react in the reverb algorithm and alters the high frequency absorbtion of the reverb space.
Set lower to reduce the amount of time high frequencies live in the algorithm for a more natural room reverb.
Alt Function: Vibrato Depth. Adds vibrato to the reverb input for lush, haunting trails

Swell LED / Alt Function Switch:

Switch LED ON when Swell is active. Alt Functions are only accessible when ALT (HOLD) is held

Bypass LED / Algorithm Select Switch:

Switch LED indicates Bypass status. Small LEDs indicate an active algorithm

Swell Switch:

Press to engage the auto swell function. Hold to maximize Space Decay sustain

Bypass Switch:

Processes signal when LED is ON passes dry signal entirely in analog (buffered or relay) when OFF
