Shopping for a British distortion pedal? Try NUX Brownie!
Classical British rock tones of 1970’s are packed into this little box.


How it works?
By using a hybrid of circuits, we create preamp and power tube distortion characteristics. You’ll be amazed to hear the warm and organic tone reproduced by it.

A special designed BJT input stage makes this distortion pedal breakup in a way when the preamp tube starts to distort. Also, Brownie has an asymmetrical clipping circuit with which you can simulate some of the characteristics of a tube amplifier. It can also keep the bottom tight by processing bass frequencies from getting muddy when they are distorted.

NUX Brownie uses a low-pass tone control filter to simulate the Variac effect (lower the voltage going into the amplifier) for rounding of your tone. The range of tone is controlled yet very useful in dialing the high end response.

The power clipping circuit is crafted from modern low noise op-amp and two red LED. It can create symmetrical clipping that distort both half of the signal and keep the sound smooth. True bypass circuits with a high quality TPDP mechanical foot switch makes the bypass signal clarity.
