The Marshall RG-1 Regenerator is a modulation pedal made by Marshall Amplification, the company better known for its amplifiers. Rather than a single effect, it covers a range of modulation sounds in one box, including chorus, flanger and phaser settings, which places it alongside multi-effect modulation units rather than a straightforward chorus pedal or flanger.1
What it does
The RG-1 Regenerator is a modulation pedal, meaning it shapes the guitar signal by varying it over time. It is made by Marshall Amplification, and its Right output is buffered and provides effect spill-over when the pedal is used in mono operation. The RG-1 comes with an easy-to-read owner's manual describing its features, settings, power connectors, signal level tips, and sample sound settings.1
The pedal's two outputs give it some flexibility. As Kahn described it:
"the second output (Right) is buffered and provides effect spill-over"
That means in mono operation the Right output keeps the effect's tail ringing after the pedal is switched off, instead of cutting it abruptly. A buffer also helps preserve signal strength over long cable runs, the same job a dedicated buffer pedal does1.
The RG-1 comes with an owner's manual that describes its features, settings, power connections, signal level tips and sample sound settings, which is useful for a player dialing in modulation sounds for the first time.1

Questions
What does the Marshall Regenerator do?
The Marshall RG-1 Regenerator is a modulation pedal that puts several modulation effects, including chorus, flanger and phaser sounds, into a single unit. It was made by Marshall Amplification, better known for amplifiers, and reviewed by MusicPlayers.com in 2007.
Does the Marshall Regenerator have a buffered output?
Yes. In mono operation the second output, labeled Right, is buffered and provides effect spill-over, so the effect tail continues after you switch the pedal off.
