Built. I had to combine some resistors, but all the values match the layout. It works with both THAT2181LB and THAT2181C.
This is my noisiest pickup. It's a Strat with a hot Quarter Pounder single coil, into a Dual Rectifier half stack on max gain. The Decimator is in the effects loop. Playing it feels totally natural, without any choppiness.
The signal dies for me when I move the threshold over 1 o'clock, no matter where the pedal is: loop or 1st in line. It does an amazing job otherwise, even on previously impossible setups with a distortion slamming into a driven lead channel. It's dead quiet now.
