Presenting the QB-1 Volume & Power Companies first musical filter effect. Combining envelope detection and external expression pedal control of the voltage controlled filter to create a unique hybrid wah / filter effect pedal.

There are seven on board controls, five potentiometers and two three-position toggle switches. The potentiometers determine the LVL (volume) of the device, TRIM (Q start point), HZ (frequency set point) which is disabled when an expression pedal is connected and ENV (envelope detector sensitivity). The two toggle switches allow you to alter the twin t-filters capacitor values which are highly interactive with the TRIM and GAIN pots giving the user a high degree of control over their sound.

When no expression pedal is connected to the device and the envelope sensitivity is set to zero the HZ knob can be used to turn the effect into a locked wah or midrange booster.

The device is compatible with any expression pedal that is configured to work as a standard voltage divider with the tip connected to the wiper regardless of the resistance.

Check out my blog post over on our website where I discuss the development of this device and explain in depth the QB-1s various features and controls.
