I've actually had the cathode resistor fail on me previously, and the previous owner had changed it as well. I'll put a 1 watt in there. Is there anything I could do to the reverb circuit to cool it down some? It definitely sounds like it could use some cooling down... but I actually dont get that "wet" sound that you often hear with fender reverbs. is that usually just with the external reverb box going into the input?
