PEDAL MANUFACTURERS COMPETE to create the most dramatic and deranged modulation effects, but not all players want their sound to be dominated by vertigo-inducing sonic mayhem. This is what makes Marshall's Regenerator unique. The tones in its six modes-Vintage Chorus, Multi-Chorus, Vintage Flanger, Phaser, Step Phaser and Vintage Vibe-are reserved at all but the most extreme settings. The pedal has controls for speed, depth and regen and an expression pedal input.
