Hi Myles,
Do you perhaps have a schematic/parts list for the Rocktron Hush IIB?
The IIB has a bad physical design, and the two pots(threshold and Filter HZ) got ripped apart because they are fastened to the board AND the front panel causing stress.
I can't tell what their values are from looking at the remains, and I can't find anything on the web. (I do have an email in to Rocktron, but I'm not holding my breath since this is discontinued)
thanks either way,
Jeff
