So I was watching that demo of Matt Bellamy's newest Manson and I just can't find answers for this anywhere.

When the guy used the 'hold' button to get a lofi sound out of the guitar, what actual circuit is being used in there? What's the nearest effect pedal that could emulate that sort of sound?

Cheers guys
That "lo-fi" sound is usually a crunchy distortion with all the bass and treble removed with some EQing, so that it sounds like the guitar is coming from a small radio
