The sustain pedal is broken on my PX-700 and I would like to know if there are any replacement pedals on the market that are compatible?
Getting back to the Casio PX-700 - yes it is possible to use a new £14.30 (EBAY) metal pedal which is more durable than the original.
The original pedal has two internal switches (semi-sustain, full sustain) depending on pedal position.
The replacement single-switch pedal is switcheable (normally open or closed) - for this mod, it should be set to 'normally OPEN'.
There are now 2 choices:
i) Are you just interested in Sustain only?
ii) Do you need the other 2 pedals working (mid/left hand)?
For choice i)
Turn off power. You can now cut the old cable where it enters the pedal assembly & remove the pedal bar (held by 2 large screws).
Discard the pedal bar & old pedals.
Open new pedal base & desolder the screened cable (note the screen connection pad position).
a) Run the black cable wire to the new pedal screen pad & solder in place.
b) Join the grey & brown wires & solder to the other pad.
Insulate the unused (yellow/red) wires.
Replace pedal base - JOB DONE!
For choice ii)
a) Dismantle pedal assembly
b) Without removing any wires, solder the two pedal wires to the existing coloured wires as described above - OK to join grey & brown wires.
Problem. The above pedal is 9" overall, so may be placed sideways, so as not to be too far forward.
OR use a smaller guitar-type footswitch (non-latching, normally open).
