I'm hoping that I can find out if there is a link to a wiring schematic and also owner's handbook that would/could have come with this guitar when it was new. Guitar plays beautifully but I suspect that the tone toggle-switch is not functioning properly as two out of the three positions sound practically identical. Also, three-way switch near input jack mutes in center position but sounds same tone in other two positions.
Any assistance, suggestions, links to the above info. sites will be greatly appreciated.
Thank you.

Hey Topcat!

The tone switch will give you three options: clean (middle), a little bit roll off (down), a lot of roll off (up). Basically it just switches between one of two caps or no caps at all.
Whether you hear the differences or not also depends a lot on the amp you're playing through.

Here are the schematics:

if you don't have a standby switch:

Wow, Thanks a bunch, Michiel. The wiring diagram for CG with standby switch was exactly what I was hoping for. Fantastic! Also, thanks for the information on playing around with different amps. I hadn't tried that. Right now I'm using a Marshall because I like the sound when playing my Les Paul and ES335 through this particular setup.
Anyway, I will definitely see if the tone changes/roll-off is more evident with one of my other amps.
Thanks again. TC

Hi Michiel,
Well, just as you suggested, I tried playing through a few different amps and it was amazing how well the differences in 'roll-off' were. Most noticeable different tones came through on my original 1967 blackface Fender Deluxe Reverb-Amp, closely followed by Mesa Dual Rectifier Maveric. Not so noticeable through my modern Fender 'Super Sonic' or Peavey 'Classic 50' (A clone of a vintage Fender Bassman)
So, thanks again for all the great information you have passed on to me. Life is good! Aloha. TC
