No that didnt work, theyre obviously doing something.
It does zero as its at the middle point between the other two taps, but it also moves from 0-5 depending on wiper movement (theres 5K to both the 0 and 10K point).
If you look at the schematic (that I wont pretend to understand fully) theres nothing else from the pots connected to the LFO ( +/- 10 on the schematic) than the 4 line.
So Im thinking the 4th and 8th terminals is used as both a center and as mod amount somehow.
