Could this have maybe been caused by the reverb pot being stripped out? r58 looks fine.
Yes, R58 was burned up and replaced with a 1 watt. The 1 watt resistor is starting to show signs of getting hot. R59 and R60 are part of the power section coming off of the transformer, doubtfull that is a result of the reverb pot. I see on the trace side of my board there is some slight discoloration on those 2 resistors possibly from heat. Do you have a picture of that area of your board?
