The effect in this video was inspired by the keyboard sound in the 1972 Led Zeppelin song “No Quarter”.
The keyboard they used was a Fender Rhodes electric piano with through a Maestro phase sifter on the fast setting.

Below are the EHX settings I found reminiscent of that great recording.
(The controls need to be fine tuned for each individuals instrument and playback equipment.)






The second example in the video was the same as above but with the Pulsar pedal warble effect.
It has more of a traditional, slightly dirty suitcase style Fender Rhodes.

The solo sound was the guitar through a Voice Box pedal in the whistle mode.
To plug a guitar into the mic jack of this pedal, I used XLR to 1/4 inch adapter plugs.
Below are the setting used for the Whistle sound.



Good luck and have fun.
