I just wonder if the Elk that Kit Rae traced had the 330pf cap on the tone section as a production error and it was supposed to be 3.3nf the whole time.
+1. I think the resulting schematic was designed to match the sound of the source, not the exact circuit. My Sustainar build has 660p for that cap. 330p wasn’t too good to my ears. I’m looking forward to comparing the two.
