I have an iSP Noise Reducer on my bench for popping problems when set to dBs above -40 or so. Since the closest schematic available to the V1 I could find is the G-String I'd like to work on a more accurate schem via this thread. A lot of people have had problems with other schematics out there so I'm hoping to provide some valuable material for debugging/troubleshooting as well as for those that want to take on the task of diy-ing it. Let's work together, cheers!
They (ISP)seem to be very protective, any schematics that have been posted in the past have been quickly taken down from what I understand.

^Noted. I'll continue on for personal information but won't be posting the schematic here. I'll be documenting how the noise suppressor operates on here at least, without the help of the schematic. Please message me for any further information.
It's been done, and was posted here, but that thread got removed (or was lost in a data issue maybe?). Parts of it are still on the wayback machine but I don't know how to find it there (I remember seeing it at one point in time). I think the other forum may still have a project for it.
EDIT: We have http://www.diystompboxes.com/smfforum/index.php?topic=114686.0. And there's: http://revolutiondeux.blogspot.ca/2012/07/isp-decimator-noise-reduction-system.html where there's a verified schematic for the original and a workalike schematic for the g-string.
