Clean or dirty boost from one control!
NVMBR Gain is a unique boost design that not only provides clean volume, but also adds a hint of sparkly overdrive. Volume increases transparently until the breaking point where overdrive begins.  Use it with the knob all the way down to maintain signal chain integrity (like a buffer), turn it up a bit for clean boost or to push an amp, or set it past 2 o'clock for a just-breaking-up sound.

The relationship of volume and overdrive is nonlinear with respect to the control knob. Volume increases in a logarithmic fashion, while overdrive increases exponentially. You can get a clean boost for the first half of the control knob travel, then a subtle amount of soft clipping drive is layered in until dominating at the extreme setting.


The nonlinear amplification control knob adds clean boost & slowly layers in a soft clipping overdrive.
