If someone has taken one apart then they may be of more use than me,
but putting a multimeter on the pedal shows that the cable ring has a
1k resistor connected to the screen when the high hat is closed.  The
resistance progressively reduces down to 1k as the high hat is closed.
 The tip is strange because that also reduces as the high hat is
closed, but only as low as 150k.  I am not sure if one is position and
the other is pressure sensitive.  So if you can lay your hands on a
couple of resistors you should at least be able to fudge it shut (1k &
150k).  A couple of potentiometers and you could make your own.

If I get chance I will open mine up.
