Hey guys...just wondering if any of you MB owners have had this happen to you?
Every time I turn my rig on, I get a louder-than-hell popping sound from my speakers. I ain't kidding...it moves air!!
The amp sounds great and I love the HUGE array of different tones the modern/classic/blend is capable of, but I'm afraid that the pop will damage the speakers and that it may be a symptom of some other problem.
I've made a habit of turning all of my volumes down before I power down, but even when I do, it still pops when I power back up!
Any ideas? It's an MB450 into a MBC410 and MBC115. I use the supplied power cord run through a fused power strip. Thanks in advance...E207

Well, before taking it to my local warranty center, I tried every combination of shut-down procedure I could think of: volumes down; leaving it on Classic (or Modern or Blend); using a power bar; plugging directly into the wall; etc. No matter what I tried, about 7 out of 10 times,
it sounded like a gunshot!!!
The warranty center said they
were able to duplicate the "gunshot", but nothing inside the amp was amiss, so they called Marshall, who said it was a "normal occurrence" with solid state power amps, but I'm skeptical.
Why would the warranty center lie, because they make money from Marshall when they fix something, thus in this case they made nothing.
Any ideas anyone? Thanks in adavnce...207
