Heads up Builders widely report inconsistent quality from PCB Guitar Mania boards, and whether a given board works is a gamble. Read recent forum reports before ordering.
From the vendor
Project overview
The No-noise gate has been designed based on the classic MXR Noise Gate. Tame down all the unwanted noises of your signal chain, hum, hizz, and all those uncomfortable noises usually associated with the high gain drives.
Introduction
• Tight Fit, designed for a 1590B enclosure, yet small enough to fit in thesame enclosure after a high gain drive.
• Ready to be wired as True Bypass.
• Works based on a Dual Op Amp, 2 2n3904 transistors, and a JFET 2n5485.
Controls
• POT1
