Anyone using Weiss 501/502 De-esser to tame sibilance?

I have used it on occasion with my Weiss Helios, it’s quite effective.  I would imagine the DSP algorithms are the same across products but not positive.  You should email Weiss, chances are you will hear from Mr. Daniel Weiss directly.

Thanks for your comments. 

Sorry, I have not used the Weiss products, but FWIW, if sibilance is a significant enough issue in your system, I would examine the whole chain to see if it is being caused by a specific component. I have no detectable sibilance in my system, but then my ears aren’t what they used to be on the higher frequencies.
