The Lil Guy is designed to give you the most of your signal in the least amount of space. We gave it 40dB of volume with a buffered output and true bypass. Its a flexible tool that gives you the most of what you want without compromising your tone.
Fully counter-clockwise is a buffered unity gain.
Fully clock-wise is 40dB of volume to do with whatever you wish. Just use it responsibly. Or don't. I'm just a website, man.
