John G	Re: Fender "75" mods Kevin, There is a possibility that the opto coupler in the cold leg of the lead ch M/V is not working. Check to see if the volts change on the led side when the f/s is activated. When the lead ch is selected and the volume is high try the lead m/v control, if there is no control then it is the opto or wireing or the f/w. Putting a temp link from the cold end of the M/V pot to grnd should make the control function correctly. Also check for dry joints around the opto. John G
