Hi guys,

I have just picked up an EDA900, and I am trying to figure out a few of the controls. I have downloaded the wiring diagram, but I am still not sure what the Magnetic Tone achieves, or the two blue trim pots in the main cavity are for. Can anybody point me in the right direction?

Regards,
Ben

It is probably to control the piezo and magnetic master volumes, in order to better balance them out.

Magnetic tone is a tone control that applies only to the magnetic pickups and not the piezos.
