The MM-6 is a phaser effect pedal made by Mode Machines, a compact unit the maker offered for guitar, bass, keyboards and even vocals. It is a simple design: one knob sets the overall effect rate, and a footswitch turns the effect on and off. The pedal is now discontinued, and its page sits in the discontinued products section of the Mode Machines site.1
What it does and who it suits
A phaser sweeps notches through a signal's frequency content, producing the sweeping, whooshing modulation tone familiar from phaser pedals of every era. Mode Machines positioned the MM-6 as a multi-instrument effect: "Works great with guitars, bass, keyboards and even vocals," according to the maker's product page.1 Its nominal input and output levels are both -20dBV, and the 1M ohm input impedance is in the range typical for a guitar at the front of a chain.1
Controls and connections
The MM-6 keeps its front panel to a minimum.
| Control | What it does |
|---|---|
| Built-in knob | Controls the overall effect rate1 |
| On/off switch | An easy to access footswitch that changes the status from off to on1 |
Connections and signal levels:
| Jack | Detail |
|---|---|
| Input | 1/4 inch monaural jack, impedance 1M ohm1 |
| Output | 1/4 inch monaural jack, impedance 10K ohm1 |
True bypass switching means the pedal should sit cleanly on a board without loading the guitar's signal when off.1
Power and build
The MM-6 runs on a 9V DC AC adapter and draws 5mA.1 There is no battery option listed, so plan a power supply spot on a pedalboard. The enclosure is a full metal shell.1
The MM-6 is discontinued. Mode Machines documents it on its discontinued products pages, so it is no longer part of the maker's current lineup.1

Questions
Is the Mode Machines MM-6 true bypass?
Yes. Mode Machines lists the MM-6 as true bypass, so when the effect is switched off the input jack connects straight to the output jack and your guitar's signal passes through untouched. The switching is done by an easy to access on/off footswitch that changes the pedal from off to on.
How much current does the MM-6 draw?
The MM-6 draws 5mA, according to Mode Machines' product page. It runs on a 9V DC AC adapter. That low draw means it puts very little demand on a power supply, though the maker specifies an adapter rather than battery power.
Is the Mode Machines MM-6 discontinued?
Yes. The MM-6 appears on Mode Machines' website under its discontinued products, so the pedal is no longer in current production. It remains documented there with its full specifications.
What are the input and output impedances of the MM-6?
The input is a 1/4 inch monaural jack with an impedance of 1M ohm, and the output is a 1/4 inch monaural jack with an impedance of 10K ohm, as listed by Mode Machines.
Can the MM-6 be used with keyboards or vocals?
Yes. Mode Machines says the MM-6 'works great with guitars, bass, keyboards and even vocals.' Its 1/4 inch jacks and nominal input and output levels of -20dBV suit line sources as well as a guitar.
