Leslie horn on top a lowrey organ mod.

i like! cool mod care to share more details on the implementation such as x-over details and speed control motor wiring (seems like it's controlled via the organ?)

Hey thanks for the reply!
It's really easy to do. The x-over is a homemade -12db @ 800hz linkwitz riley. The switch for slow/fast is also a homemade box using a 120VAC SPDT relay connected to a SPDT footswitch. There are a few ways you can wire it. I have the footswitch and motors connected to the relay which switches the speed. Everything is completely separate from the organ itself.
