The JoshWah is an envelope filter (auto-wah) with a gain stage on the input for increased harmonics and envelope detection. It uses a resonant low pass filter for fast up-sweeps.
The Gain control will boost your signal before feeding the filter. The amount of boost can range from light overdrive to full saturation. At the minimum setting, your input signal is left clean at unity gain.
The Sense control is used for setting up the optimal envelope sweep. With no gain, start with the sense control at noon and adjust until the maximum sweep is obtained.
The Peak control increases the amount of resonance at the cutoff frequency. This makes the wah effect more pronounced.
The Freq control determines the frequency range of the sweep.
The Release control sets the time it takes for the filter to reset to the lowest frequency after an up-sweep.
The Volume control sets the output level of the pedal.
The pedal requires a 9V DC power supply (not included). The DC supply should be a standard Boss style connector, center negative polarity. The current draw is approximately 30 mA.
The JoshWah has a true bypass switch.
