Hey all,
So Ive had my Mark III Blue stripe for a few weeks now and it has been in my former bands practice spot. They haven't used it much, nor have I.
Now the guy I purchased it from said it just came back from Mesa, where it was serviced and given a clean bill of health by Mike B.
Having played it myself, there seemed to be no issues.It could be cranked, it could whisper and all else between. No problems. Tubes sounded good and everything worked as it should.
Fast forward to this weekend. They took it to a recording session and gave it back to me. I plug in in today and NOTHING.
Not a single note, cough, fart, nothing. I figured there was a knob turned down, effects send issue, nothing... All tubes are fit snugly into place. everything is where it should be. Nothing. All I can hear now is a hum, yes, just a hum coming from inside the chassis, not through the speaker. That worries me like all hell. I figure something is wrong inside because usually a natural hum from the output will get louder as I turn up the master. This does not. It's definitely something wrong in the amp.
I've tried trouble shooting with new cables, new guitar, nothing again. Hum continues, in either class A or simul class. I cannot for the life of me figure out the issue.
I suspect they blew something, perhaps by unplugging the internal speaker and leaving the amp on. They're not complete idiots, but I've seen them do silly things with amps before. Any ideas before I take it to my tech?
