    My story so far.....

    I bought a used M9 and it was the best sounding amp I have ever heard. It died on a gig a few weeks after I bought it used and luckily the great store I bought it from (Long & McQuade in Oshawa, Canada) set things right and ordered me a brand new M9 from Mesa.

    Got my new Mesa a few months back and it has been perfect in every way..... Until tonight.:spit:

    Sooooo.... I plugged in tonight in my studio to practice and the amp wouldn't work. No sound at all but powered up. After playing around for a bit, powering down, unplugging, etc.... I found the problem.

    If I turned the compressor off, the amp worked fine. If I turned the compressor on and turned the ratio knob to 0, it also worked fine. As soon as the ratio knob was turned up a hair, the red compressor light came on and no output!

    Before I throw this @$&?%#! thing out the window, any ideas? I don't think it is a fuse issue, but..... HELP!!!!!

    I am really getting pissed as I just bought Mesa 410 and 115 cabs also..... Almost $3k invested in Mesa gear.... And the M9 is by far the flakiest head I have ever owned.

    Please tell me I am mental and the answer to my issue will make me feel like a moron!

    P.S. The Mesa in question was made on 7-7-11 and is S/N 1007.

    If it was made on 7-7-12 as you claim, it is from the future......

    I would contact Mesa Support tomorrow and confirm its the latest upgraded amp. I have x2 M9's and they are running pretty flawless. After the updates, they should run very stable and cooler. I know a lot of others that also say the same after the upgrades and we play LOUD.

    Sorry to hear your amp letting you down! I am understand your frustration, but it could happen with any amp. I am using Mesa gear long time now, M-Pulse, M6, M9 and never had any, and such this issue. The best if you call Mesa, I am sure they will help you out and will fix this problem for you.

    Fixed. 7-7-11!:bag:

    I hope the 7-7-12 future M9's are better than mine!

    I will call them for sure but this amp was made in July 2011..... Has ALL of the fixes based on the build date.

    Worst part is... It seems to be working perfectly now. I posted more details in the M9 thread, but it has been a weird experience.... Crazy noises, crackling.... Then, fine!

    Contact Mesa support and state exactly what you said here. First thing I would do is eliminate everything but the bass and amp. Bass - cable - amp - cab. Play for a bit and see if you can reproduce the issues. Start eliminating as it could be something other than the amp also. Just an observation from experience myself. Good luck!

    Maybe every M9 should come with.........a 2nd as a spare for when #1 returns to Mesa:rollno::bawl::mad:

    Hope it ends well.

    Just a stab in the dark here, but...did you happen to have the amp stored in a cold area (garage, car, etc.) prior to bringing it into your studio? If that's the case and it didn't have time to warm up, perhaps some condensation formed within the amp and caused the issue.

    At any rate, good luck with getting it resolved.

    I hate reading about all the issues with M9's. I've had an M6 for the past 1.5 years (about 100 gigs) and it's worked flawlessly.

    Wow, I have a M9 that never skips a beat, and I play 2-3 times a week for a year on the unit. I understand mesa is great about making things right so call them.

    That's a good idea lomo. I love this thing so much I'm considering having 2 to keep 1 going at all times. Not many amps I'd say that about.

    Just got a call from L&M where my amp went for service and it was apparently fixed in record time.... the problem was a loose nut thet was toughing the front of the circuitboard.

    I am trusting that it will be good now as the amp tech really knows his stuff.

    If it blows up again, I will open a new whiny Mesa bashing thread, but I will close this one hoping my amp is perfect for years to come!
