    Also toggling causes the gate to jump from 0.6mV to -5V
    To be clear, is this the original footswitch? Does it have LEDs or just open/short switch?

      Not the original footswitch. I am using a standard 2 button footswitch with no LED.

        Seems like the gate should go to -15.6V with the FS in the open position. With -5V there it seems like the gate of the FET is blown (which could explain that big thump when switched). Seems like that part needs to get replaced. I think any xx4093 part should work there (N channel JFET) but others can correct me if I'm wrong.

          Seems that a lot of vendors are selling the J113.

            Can I use a J111 in place of a J113?

              Replaced with J111 and all good.

              Thank you all.
