We covered French manufacturer Glou Glou in the past for their truly remarkable Rendez Vous pedal, and therefore we are eager to see what kind of sonic magic their new device Pralines can deliver.

With its name and color inspired by a classic dessert from southern France, this effect consists of four parallel resonant band-pass filters, but there is a lot more to it:

FILTERS
Each filter can be set on a separate frequency (4 small Freq knobs), but they have a shared volume and resonance control (Filters  and  Peak knobs). Resonant filter circuits are normally found on synthesizers.

MODULATION
The Big “Mod” Knob on the bottom left controls what kind of modulation is applied to the filters (the choices are envelope down, envelope up, LFO, expression pedal);

The LFO CTRL section on the bottom right consists of a Speed mini-knob, a Fast/Slow Switch, and a bigger knob that selects from three LFO Modes: Envelop Up, Envelop Down and Expression pedal. (We assume that the “Envelope” modes are linked to the Sensitivity knob on the top right of the Pralines).
Each filter has a separate Mini-Modulation knob that makes it more or less “wet.”

FUZZ
The noise seekers among you will be happy to know that there is a toggle switch that activates a gated fuzz (which can be easily triggered with the foot)

This is obviously a very creative pedal that can be used with both guitars and synths to forge sounds from the unconventional to the atmospheric. A bunch of videographers shot demo of videos of it in the last few days, here are a few of our favorites:

FILTERS

Each filter frequency can be controlled independently.
These 4 small FREQ knobs set the base frequency of each filter.
The base frequency will then be modulated according to the 4 small MOD knobs.

The PEAK knob controls the global resonance of the filter.
When fully CW, filters self-oscillation occurs and you now have 4 controllable sine-wave VCO’s.

The MIX knob is used to blend the out-of-phase dry signal with the filtered signal. At low PEAK settings, phase cancellation occurs and it’s capable of producing phaser/vibrato sounds.

It’s a basic PNP transistor gated fuzz.
The FUZZ knob changes the fuzz texture from soft saturation to hard squared fuzz
The gate starts to engage around 12 o’clock.

The Mod rotary switch selects which modulation is applied to filters: envelope down, envelope up, LFO, expression pedal.

Triangle LFO with two frequency ranges. LFO frequency is set by the small SPEED knob and can be controlled by envelope down, envelope up and expression pedal

SENS
 sets the sensitivity of the envelope generator which is followed by a slew limiter that will slow/smooth the envelope on ATTACK and DECAY.
