26 GaryE 5 months ago Dave, can you also please send the tremolo fix to me? Thanks. Hey guys . I’m the tech that Paul had his Gretsch modded.Here’s what I have done to Fender amps and the Executive. As for the Reverb,it was a hum issue, it was just a matter of moving a ground wire on the foot switch jack I believe. It has been a while ! There's a Fender service bulletin on this from way back.The official Fender solution (Service Bulletin number 9) "The ticking caused by the Vibrato is caused by improper lead dress.It can almost be "cured" by connecting a .01 mfd 600 volt mylar capacitor on the 10 meg ohm resistor in the vibrato circuit. this resistor is located on the parts panel. Remove capacitor across the 10 meg ohm resistor (old modification) if in place."(That is, run the cap from the junction of the 10 meg resistor and the optoisolator to ground.)"If this does not produce the desired results, then the leads should be dressed as follows and excessive lengths shortened. Dress the leads to the vibrato speed and intensity controls away from the tone controls and filter leads. "Bunch" the leads to the components on the parts panel which connect to the tube socket of the 7025 (12AX7) vibrato tube.
