By using a hybrid of circuits, we created truly unique pre-amp and power tube distortion characteristics. You’ll be amazed to hear the warm, organic tone that’s reproduced.
Brownie has a specially designed BJT input stage causing it to “break-up” when the preamp tube starts to distort. It also has an asymmetrical clipping circuit letting you simulate some of the characteristics of an actual tube amplifier. It also keeps the bottom-end tight by processing bass frequencies which can get muddy when distorted.
Nux Brownie uses a low-pass tone control filter to simulate the Variac effect (by lowering the voltage going into the amplifier) for rounding-off your tone. The range of tone is controlled yet perfect for dialing-in the high-end response.
The power clipping circuit is crafted from a modern low-noise op-amp and 2 red LEDs. It can create symmetrical clipping that distorts both halves of the signal keeping the sound smooth. True bypass circuits with a high quality TPDP mechanical foot-switch gives the bypass its phenomenal signal clarity.
