Here’s my take on a modded version of the MXR Noise Gate based on the tonepad schematics, yet to be verified. I decided to incorporate most of the suggested mods forgoing only the “momentary” switch. Excited to find out whether this one works or not. Let me know if you build it.
Update (08.10.2011): Built this one today and it seems to work. It removes noise, but the additional controls didn’t initially seem to do much. This was probably because of my very rudimentary test setup though. I’m calling this one verified.
