    The wonderful static discharge abilities of the faithful 2M2 are sadly under appreciated.

    I unsuccessfully tried to get a 2M pot today from Jaycar.... Seems RS is the only reasonable alternative...

    For sure, I could have used a couple of 1M resistors, but when nothing is plugged into the send and return sockets, the two resistors would effectively be in parallel with each other, giving a load-resistance of around 500k, with two 2M2 resistors the load resistance is around 1.1M, both 500k and 1.1M would constitute a relatively light load to the signal coming from the preamp, but since the preamp signal is buffered by a 2N5087 PNP transistor configured as an emitter-follower stage, the loading would have been inconsequential, I went with the 2M2 resistors anyway.
