Attention:
These fader-units/chassis'  have originally been made using a different fader. The P&Gs have been retrofitted
and while they have slightly different sizes, there has been some drilling at one mounting screw and
the fader does not use the entire scale as printed on the chassis.
The pick-up for the fader knob has been cut. Restoring this petal part is possible or use the knob
that comes with the chassis.

All this is why you'll get these chassis for free when you buy the faders.
