I also have a Yamaha RGX (very similar to the Ibanez) guitar. It has a clear
plastic sheet which covers the whole of the top surface of the body under which
you can put various designs (I think Yamaha called it the "Free Art Guitar"),
I've chosen a floral pattern similar to that available on an Ibanez Jem. I've
also made a few modifications to the circuitry.
Basically I wanted to get all the 3 single coil tones and all the double
humbucker tones and then some, without drilling holes in the guitar.
I purchased two push-push pots from Chandler Guitars and set about
devising a circuit . I've had several attempts so far an the one I've settled on
gives the following options:
With the volume pot out, I get the conventional single coil selections: neck
on its own, neck and middle, middle on its own, middle and bridge and bridge on
its own. The tone pot switch reverses the phase of the neck humbucker, this
means in position 5 you can select which of the neck coils is used in single
coil mode and in position 4 you can get the middle and nearest neck coil out of
With the volume pot in, I get the basic dual humbucker tones: neck, neck and
bridge and bridge on its own.
In this mode the tone pot acts as a conventional phase switch for the neck
and bridge selection. Positions 1,2 and 3 in this mode all give you the same
bridge humbucker only setting but this is quite useful as you can select
position 2 and go into classic bridge and middle single coil mode just by the
push of the volume pot!
