I designed this guitar pedal for a friend in a pop-punk/alt-rock band who wanted to emulate the distorted radio sound that is common in those genres, for example the first 3 seconds of the intro riff of Green Day's "American Idiot".
To really dig into that transistor sound I designed a unique crossover distortion circuit, enabling players to tune in how crappy they want their tone.
- High and Low-pass tuneable Sallen-Key filters for reducing the bandwidth of the guitar
- Resonance control to tune in just how nasaly you want that radio to sound
- Crossover distortion circuit for adding crappy crunch to your tone
The name is a reference to Dan Simmons' Hyperion Cantos where the fatline is the the communication medium used between planets, operating "faster than light" -> FTL -> fatline. I think this fits quite well as I have overengineered a radio simulator with (relatively) futuristic technology.
