X-Blender operates in both Series and Parallel modes. Series mode is a simple effects loop, and all of X-Blender's controls are disabled. This mode is true bypass, with no buffering. Parallel mode introduces a buffer into your signal. In this mode, you can use the pedal's Dry/Wet knob to control the mixture of dry signal and affected signal. A 2-band EQ and Volume control tailor your affected signal to taste. A Boost switch provides a +6dB boost. A Phase Invert switch flips your signal's polarity - great for correcting the unwanted side effects that are often created by vintage-type wah or booster devices.
