progress so far:
I managed to get the service manual from fender by invoking the new EU "right to repair regulations" It wasnt any help as regards troubleshooting, apparently the board is non-repairable. It did however have full schematic and component values. So, I replaced the 130 ohm resistor. The new one turned red hot and fried as soon as voltage applied.
i then replaced u40, the regulator. resistor no longer frying but burnt my finger when touched.
i have now found shorted capacitor c285. 220uF 25v. waiting on replacement part to arrive.
fingers crossed, that will do the trick

Hi all
My first post!

I've got a fender GDEC 3 thirty. It's got very attenuated volume.

There is a fried resistor on the main board beside a voltage regulator. It's Crispy so I can't read the colour bands.  It's R269 so I'm looking for a schematic to see what it's value is.

I found a schematic but it must be  older/newer since it didn't have that resistor.
Any help much appreciated.
Cheers
