Default external pitch on a turntable


I just bought a Vestax PDX 2000 mk2, and I would like to modify the pitch control.
Actually, I want to control the "ultra pitch" (+/- 50%) with an external device. So, there is 2 options:

1) desolder the actual fader and replace it with the same kind of potentiometer (100k if the actual one is a 100k)

2) directly plug the new device on the motor without desoldering anything

Option 2 would be the best one for me, so that I could switch between my device and the normal fader that is already in the turntable, with a simple on/off button.

The problem is I do not know how this turntable really works, and how the pitch could be controlled.

I just know this is a direct drive DC motor.

Does anyone knows a little bit more about pitch devices on turntables?

Thank you for helping

The direct drive DC motor is in fact an AC motor powered by an inverter.
It is not possible to modify the motor.
You can just plug the potentiometer outside the turntable.
