[sdiy] Yamaha CS80

[Lincoln Fong]

I've been given a CS80 for a short while with no footpedals or instructions.
On the front someone has put a label: 'Important, connect footpedals before
switching on'. As a bodge can I put a tip-ring shorted quarter inch jack in
the footpedal (expression) socket or is there something special about the
proper pedal? Is it just a potential divider and where can I get one? I know
a volume pedal could be rewired but would this give an adequate range from
nothing to full level?

I'm assuming no sound will come out without the pedal and that no harm would
actually occur if it were switched on.

Thanks,

Lincoln
