Can my Wiggler be modded to have an expression control jack?

all 3 lugs of the rate-pot (1k, IIRC) need to be switched out,
and the connections routed to the external (pedal-)pot,
while none of the 3 connections are connected to ground!

if one would find a free space to mount an isolated stereo-switch-jack
into the chassis,
a short stereo-cable from Wiggler to rocker-pedal
is probably possible,
since the impedance is quite low (1k).

the ccw lug ought to be soldered to the screen (shield) of the stereo-cable,
and plastic (isolated) plugs should be used to avoid anything grounded
touching the circuitry.

also in the rocker-pedal, an isolated stereo-jack ought to be used.
(or better: a fixed cable)
