SOLD Pre-Fender SWR SM-500, rack bag - $250

Up for sale is my 1999 Pre-Fender SWR SM 500 in good condition w/ a slight ground buzz (see disclosures). I purchased this brand new in 1999 and it has been my main head since then, although I haven't really used it much in the last few years and it has been kept in a rack bag (which I'm including, although one of the cover panels is missing). Ships with a brand new Tung Sol preamp tube installed. I have recently purchased an Ampeg PF-500, so I really don't need this anymore.

Disclosures on condition:

-minimal cosmetic wear; standard player scratches/dings here and there

-mono effects return jack has always been a little loose - looks like some bad threading is not allowing the nut to fully seat the jack to the back panel. Still functional.

-concentric pot on the stereo volume control is very slightly bent, but still functional.

-a few of the small top panel screws became stripped and are missing, but there are plenty of others remaining to keep the top snug

-the "ground buzz" mentioned in the title is a 60-cycle-type hum that developed within the last couple of years, and is present through all outputs (speaker, line, effects loop). Local tech seems to think it's just a simple ground problem somewhere, but I haven't had much reason to have it put on a bench and repaired. All outputs and controls are otherwise fully functional.

Not for nuthin' but, I have that same amp with the same problem. As soon as the internal cooling fan came on..huge 60hz buzz.

Turned out to be a ground loop The coating on the face plate is thick and TOUGH. I actually had to put star washers behind the rack screws so it would bite through that paint and into the metal. It hasn't made a peep since.
