In addition to the high-quality metal bypass switch, the Brown Dog has four knobs and a switch:

The dirty level controls the volume of the signal coming from the Brown Dog’s fuzz circuit in the output mix. To make the fuzz louder, turn it up. To make the fuzz quieter, turn it down.

The clean level controls the volume of the original input signal in the output mix. The Brown Dog mixes the dirty signal coming from its fuzz circuit with the original input signal so you can determine exactly how much fuzz you want and keep the tone of your instrument.

The gate control governs how loud the input signal must be for a fuzz tone to be produced. Especially in hard mode, you can use this gating effect to prevent hum from your pickups and the noise of your fingers on the strings from being amplified by the fuzz circuit. You can also ensure that your notes start and end cleanly, so your bass line remains clear even though you have massive amounts of fuzz applied.

The drive control alters the character of the fuzz produced by controlling how hard the fuzz circuit is driven. Driving the fuzz harder squares off your sound more and makes it sound harsher. In hard mode with maximum drive, you can get synth-like square wave tones. In soft mode, the drive control will alter the volume of the fuzz signal and you may find you need to compensate with the dirty level control.

Use the mode switch to switch between soft and hard fuzz, which have different characters. The hard fuzz produces very square-edged acidic tones. Use it for really hardcore metal sounds or turn up the gate for some great synth tones. The soft mode produces a classic warm bass fuzz.
