Maneco Labs Grone 2 Pedal
The Maneco Labs Grone 2 Synth Pedal is not your typical stompbox. It is a dark, atmospheric sound machine that can turn a single note into a massive wall of drone, noise, and swirling ambience. You can use it as a standalone instrument or run your guitar, synth, or other gear through it for wild, evolving textures. From deep rumbling tones to haunting spacey washes, this pedal invites you to step outside the ordinary and create something truly unique.
Maneco Labs Grone 2 Review
Inspired by the original Eurorack module, the Maneco Labs Grone Drone 2 Effect Pedal brings serious sound design power to a pedalboard-friendly format. At its core is a drone oscillator built around 16 selectable equations that shape pitch and tone in unusual ways.
Three variable controls and a sample rate knob let you push the sound from slow, heavy pulses to high, glitchy chaos. An MS20-style low-pass filter adds bite and screaming resonance, while the built-in LFO keeps things moving.
Add the fuzz to dirty up incoming signals, then send everything through a rich delay and reverb section with octave up or down pitch options and a freeze function. It is deep, expressive, and built for players who want more than basic effects.

Maneco Labs Grone 2 Synthesizer Pedal Controls
The Maneco Labs Grone Drone 2 Synthesizer Pedal is packed with hands-on controls that let you shape everything from deep drones to chaotic noise walls. Here’s what each knob, switch, and jack does.
Drone VCO Section
- Algorithm: Selects one of 16 sound equations that define the core character of the drone. Four LEDs display the selected equation in binary form.
- Variables A0, A1, and A2: These three controls change the numbers used by the equation. Adjusting them reshapes the tone and pitch in unique and sometimes unpredictable ways.
- Sample Rate: This knob controls the oscillator's pitch and speed. Lower settings create slower, deeper tones. Higher settings push it into sharper, more intense territory.
- EXP 2 Input: Expression jack for controlling the oscillator sample rate in real time.
Noise Generator
- Noise Level: Adjusts the volume of the white noise that blends with the drone signal.
Filter Section
- Cut Frequency: Sets the brightness or darkness of the sound by adjusting the filter cutoff point
- Resonance: Boosts the filter peak for sharper, more pronounced tones. Higher settings can create aggressive, screaming textures.
- Modulation 1 Amount: Controls how much the LFO affects the filter cutoff.
- EXP 1 Input: Expression jack for controlling the filter cutoff with an external pedal.
LFO 1
- Rate: Sets the speed of the low-frequency modulation.
- Waveform: Selects the modulation shape for the modulation section. Options include ramp up, ramp down, square, triangle, sine, sweep, random levels, and random slopes.
Fuzz Section
- Input Gain: Adjusts how hard the incoming signal hits the fuzz circuit.
- Level: Controls the output volume of the fuzzed signal.
Effects Section
- Blend: This level control mixes the effected signal with your dry signal.
- Octave Blend: Adds in a pitched signal before it hits the reverb.
- Octave -1 / +1: Sets the pitch component either one octave down or one octave up.
- Repeat: Controls the feedback amount of the delay.
- Balance: Adjusts the mix between delay and reverb.
- Pitch: Changes the sampling rate of the entire effects section, altering delay time and reverb decay for warped textures.
Footswitches
- Synth: Turns the drone oscillator and noise generator on or off.
- Filter: Bypasses the filter section.
- Fuzz: Bypasses the fuzz section.
- Reverb: Bypasses the reverb and delay section.
- Freeze / Tap Tempo: This footswitch can operate in two modes, depending on the toggle switch position. In Freeze mode, it captures and holds the current reverb sound for endless ambient sustain. In Tap Tempo delay mode, you can tap in the delay speed with your foot, making it easy to match the timing to your playing.
Jacks
- Input Jack: Connect your instrument or external sound source.
- Output Jack: Sends the final processed signal to your amp or recording setup.
- Expression 1: Controls filter cutoff.
- Expression 2: Controls oscillator sample rate.
Maneco Labs Grone 2 Dark Drone Machine FAQs
Is the Maneco Labs Grone 2 Pedal an instrument or an effects pedal?
It can be both. You can use it as a standalone drone instrument, or plug in your guitar, synth, or other gear and use it as a powerful effects processor.
Does it need a special power supply?
It runs on a standard 9V DC center-negative power supply. The power supply is not included in the box.
Can I use an expression pedal with it?
Yes. It has two expression inputs. One controls the filter cutoff, and the other controls the oscillator sample rate for real-time pitch and speed changes.

What kind of sounds can it create?
It can produce deep drones, noisy textures, gritty fuzz tones, and huge ambient soundscapes with delay and reverb. It is great for experimental, ambient, and cinematic styles.
What does the freeze function do?
The freeze footswitch holds the current reverb sound and sustains it, letting you build long, atmospheric layers that continue underneath your playing.
Can I turn individual sections on and off?
Yes. The pedal features separate footswitches for the synth engine, filter, fuzz, and reverb sections, so you can shape your sound in stages.
