Iron Curtain is a classic, simple no-nonsense noise gate with intuitive controls, high quality components and zero tolerance for any unwanted noise in your signal - only the purest tone is welcome in the noise-free republic! Some old amplifiers or some venues just have a lot inherent noise. If the dynamics of your playing is important to you, going from a soft touch with barely audible notes and up to blasting the roof off, a good noise gate can help you keep that sonic image sharp and crisp. Iron Curtain is built on a classic all-analog circuit that will keep out any unwanted noise from your rig while letting your tone pass through completely unscathed. Featuring just a Threshold knob and a Decay knob, using Iron Curtain is simpler than most overdrive pedals. This 2-knob operation makes it easy to dial in a silent, responsive guitar sound whether you're going for a grinding metal tone with all the gain or you're simply playing in an old building with ample stage lighting, using old single coils.
