Hall effect CV pedals (was: Volume pedals for CV discussion)

[Edu Silva]

Hi, pedal gurus!

Have any of you ever tried to use a Hall effect device instead of a
potentiometer or LDR? A magnet can be glued to the underside of the pedal,
and as it is depressed, the magnet is brought closer to the Hall eff
device. The closer it is, the stronger the magnetic field is, and thus the
output voltage.

I've heard about Allegro Microsystems, that makes some Hall effect
transducers, but I never used this kind of device, so there's not much I
can say about them.
