NVMBR Gain- boost/drive
A NOVEL NONLINEAR AMP
WHAT: A mini pedal version of our 1st original design- a clean & dirty boost that can level up your tone in many ways. Preserve signal against high frequency loss, push an amp to breakup, clean boost, deliver that just breaking up sound, or light overdrive! It's like having a mini amp in your chain!
INSPIRATION: We created the NVMBR Gain circuit to provide clean boost that could also give a boosted amp sound via soft clipping overdrive- now in a mini size!
CIRCUIT SAUCE: We designed the NVMBR Gain because we wanted a boost that could transition gracefully from clean to dirty tones. Volume increases from just over unity to about 10db before soft-clipping drive starts for another 5db of boost. That clipping is barely layered in until the end of the knob rotation, where light overdrive appears exponentially- it reaches a breaking point and drive dominates. There is simultaneous control of gain and diode clipping using a dual potentiometer. It's still a 1-knobber, but that 1 knob is doing 2 things!
SOUND: With the knob all the way to the left, the NVMBR Gain can be used as a line driver to maintain signal chain integrity. Try it at the front or end of your signal chain for a tone sweetener. The left side of the control knob is clean gain- here the clipping section is inactive. The cleaner boost is useful in loops that need more volume or to drive the frontend of an amp. From about 1 o'clock onward, the soft clipping is engaged and provides subtle amounts of grit and character as you dig into strings. Towards the very end the drive will appear more present in a hurry, as the clipping section is fully unleashed. Note: Don’t put this device in front of an old school fuzz, like a fuzz face, or you may lose the cleanup effect.
The same circuit can be found with the Witch Finger graphic too!
Austere design, esoteric nomenclature.
