Kingslayer Diode Gating Issues

Hey guys, Built a Kingslayer a good while ago and wanted to test out some different diodes in it.  Currently I have a set of D9Es and a Set of OA1160s as hard clippers and a two mosfets with a bat46 on one side for soft clippers.  The pedal sounds fantastic, though Ive noticed that there is a slight gating that the diodes are doing during the decay of the notes, cutting off the sustain.  any clue as to what this would be?  I checked the usual things like IC voltages, I just didn't know if this was specific character of the diodes or if it may be something I could do to change this.  Any help you guys could give me would be greatly appreciated.

Hey there. I'm a little confused what you mean by hard vs soft clipping because the current version of the Kingslayer only has hard clipping.  Soft clipping would be in the feedback loop of the opamp. Are you using an older board?

According to the discussion it seems that as your note decays there are some high frequency spikes that occur, which goes through the clippers and you hear them as that sort of fizzy sputter as the note trails out. The suggestion is to add a low pass filter right before the clipping diodes.  So you could probably put a cap (try 1n) in parallel with the clipping diodes and see if that solves the problem for you.
