Fender Stage 160DSP - Help needed for replacement parts

[Tops3b]

I am trying to locate the right parts to replace the time/rate pot and knob on this amp. Can anyone point me in the right direction as I'm having trouble locating them. I also need to replace the cable connecting the four way switch to the amp too. Is this a regular balanced lead? Many thanks for any help!

Cheers

Richard

Time/Rate pot is R135 on the board, and is part number: 0027941000 (50kB)

Knob for it is part number 0053986000

The cable from the footswitch to the amp is a plain old vanilla guitar cord.
