MXR Noise Gate

Geiri has worked his way through with this and he offers couple pointers to enhance it, or to get it working better. So with these mods this one should get this running like intended. (I'll be fixing the layouts tonight..)

1. Important - the 2n3904 (I used 2N5088) must be matched. I made them exactly the same hFE.
2. Change 680R to 4.7K (gets rid of the oscillation problem)
3. The 1M that's going from JFET Gate (the one that goes down to the second last row, change it to 1.8K

I don't think the hFE matters, as long as it's matched. I haven't tried lower hFE. Mine are medium/high.. can't remember

Changing the 1M to 1.8K gets the level back to normal

 

First, the stock version with only the sensitivity/threshold control (it is called sensitivity in the Tonepad project files):

Then the highly modded one. With added controls for Attack, Release and Attenuation levels. Also, added momentary single pole stomp switch - This one acts as a momentary kill switch for gate.
