Essential Information About the EarthQuaker Devices Four to One Mixer
- Ultra-compact 4-channel mixer to sum up to four sources into a single output, with independent level control per channel.
- Phase inversion per channel (Phase -/+) to avoid bass dips and cancellations when mixing signals with opposite polarity.
- Wide dynamic range and design aimed at preserving signal integrity, even with long cables.
- Versatile : perfect with the One to Four Splitter for parallel processing, but also ideal for guitar, bass, synths, drum machines, and hybrid setups.

An EarthQuaker Devices Routing Tool Designed for Parallel Processing
The Four to One Mixer is not an effect pedal in the traditional sense: it is a routing tool designed to solve a very practical problem on a modern pedalboard: mixing multiple parallel paths without losing volume, without degrading the signal, and without struggling with phase issues. Paired with the One to Four Splitter (and loops like the Flexi Loops), it becomes the heart of a "wet/dry" or multi-chain system, where each color (drive, modulation, ambience, pitch, etc.) remains controllable and coherent.
Who It's For and Where the Four to One Mixer Excels
The Four to One Mixer is aimed at guitarists and bassists as well as synth and machine musicians: whenever you have multiple sources to sum cleanly, it becomes a go-to tool. Live, it simplifies parallel rigs (for example: clean tone + fuzz + octave + reverb) and allows rebalancing an overpowering preset without changing your effect settings. In the studio, it facilitates creative chains and texture blending, while maintaining a very "pedalboard friendly" approach.
Controls, Mixing Logic, and Practical Strengths
Each channel features a Level control to precisely adjust its contribution to the final mix, and a Phase -/+ selector to correct polarity if a pedal or instrument reverses phase. This detail makes all the difference: when two signals are misaligned, the mix can sound "thin," lose bass, or seem to drop in volume. Here, you fix that with a simple gesture, channel by channel. The electronics with high input impedance easily accept various instruments and help maintain a stable response, with a low output impedance useful for driving the rest of the pedalboard or a long cable run.
Sound Character
The sonic character of the Four to One Mixer is primarily transparent : the goal is to mix without coloring, respecting the dynamics and attack of your playing. It especially highlights what you build around it: a clear sound that remains defined, a highly textured effect you can finely dose, or a "special" path (octaver, shimmer, fuzz) that you add just at the right amount. And thanks to the phase selectors, you avoid mixes that "cancel out" and preserve a stronger, more musical low end.

Questions frequently asked
How to mix four effect loops in parallel on a pedalboard?
Each of the four channels has a Level control to adjust its volume in the final mix. The Four to One Mixer can be paired with the One to Four Splitter and Flexi Loops to create multiple parallel signal paths.
Does the Earthquaker Four to One Mixer fix phase issues?
Each channel features a Phase +/- switch to invert its polarity if needed. This correction helps reduce bass or volume loss caused by two misaligned signals.
What is the impedance of the Earthquaker mixer?
The input impedance is 1 MOhm and the output impedance is 100 Ohms. This low output impedance allows driving the rest of the pedalboard or a long cable length.
Can it be used with bass or synths?
Its analog electronics with high input impedance accept various sources including bass, synths, and machines. The mixer maintains a design suitable for integration on a pedalboard.
Does the mixer color the guitar signal?
The circuit is designed for transparent mixing, preserving the dynamics and attack of the signal. Each path, such as a fuzz, octave, or reverb, can thus be added with its own Level control. The phase settings help maintain a solid low end during the mix.
