The Mini Drive is a 4HP Drive/Distortion module inspired by the classic Minimoog input gain. Mini Drive has two inputs which are higher and lower gain – but if you use both they’re the same level mixed. The Drive knob goes from zero/silent to lots of gain. It’s a dirty gain for modular level and works well with line level inputs – like a drum machine. It’s not suited as an external input for guitar.
Using this module is a great way to make a polite sound source into something less polite, but always experiment with the levels! – the output can sound completely different depending on the settings and it can also be used to just add a nice bit of warmth to your input.
