I've been comparing the schematics of the EH Bassballs and the Slurpee. I noticed a 2.2M connected from input to ground. the other end is connected to a circle with the word pin inside it. The other circle with a pin inside on the schematic is connected to ground. Does that imply that both ends of the 2.2m is connected to ground? and the input also. i don't know a lot, yet, but this doesn't make sense to me.
The pins on the schematic are connected to different I/O pads on the PCB. The one connected to the 2M2 resistor is for the circuit input wire. You can just ignore them on the schem.
