BYPASSING A GAIN STAGE - QUERY

[NGW]

Hi Kevin,

The relays switch; with one on while the other is off.
Therefore: Relay 1 switches ON for Clean and Relay 2 switches OFF for clean.
Fender shows the schematic in Drive mode because that is how the voltages are to be measured.
"All voltages measured with respect to ground - Footswitch connected. Drive Ch. Sel."

I normally wire my amps your way. It is just a bit of a chore, with these Fender PCBs.
I will have a look at the degree of difficulty of cutting traces and wiring how you have suggested. 
If it is too difficult to warrant the time involved, will the changes in my Post #4 suffice without detrimental effects?

I have shown the new changes to the cct. in RED.

Thanks again for your advice.
