The ZUUL has become the standard in noise gates for today’s modern musician. Never satisfied to rest on our laurels, we are proud to bring you the ZUUL+! The ZUUL+ incorporates everything the standard ZUUL is known for, with several new added features! In addition to the KEY IN, ZUUL+ now has a KEY THRU jack with ground lift switch, eliminating the need to split the signal for the KEY using an external device and to tackle ground loops. In addition to the GATE Threshold control, ZUUL+ now also includes HOLD and RELEASE controls, allowing you to further tailor the your perfect gating action. Use in front of an amplifier or in a series effects loop in 2CM, 3CM or 4CM applications. Dual colour LED for visual feedback gating action: Green = Open, Red = Closed, Off = Bypass. The KEY IN is a buffered input that accepts signal from your guitar or other signal source which lets you go from clean to high gain without changing the GATE Threshold knob. This powerful feature lets you control the gate with a different signal than what flows through the IN/OUT top jacks of the ZUUL+. Finished off in a black gloss metal flake powder coated enclosure with raised white cream gloss screening. Proudly made in North America.
