Here's what Studiologic say about the VFP-125:
It is with good reason that the VFP 1 is the best selling pedal on the market. Relying on more then 40 years of tradition in the production of tactile interfaces for musical instruments, this pedal offers absolute perfect control. Its solid, rubberised body is strong enough to resist in a working musician environment, while its chromed lever feels just like the real thing. Contact selectable open or closed at rest.
