    I own a cat... Owned a cat........... I think it was a cat.
    Was hoping someone here could shed some light on this as I have zero idea what could have happened to cause this.

    Went to turn my amp on the other day, only play maybe once-twice a week these days, but when I turned it on, the volume output I was getting started getting lower as I was playing and seemed to bottom out at about 1/3 of the normal volume. Even with the volume knob up full blast and the gain up half way, it isn't even half as loud as it was originally.

    I have seen this happen on stereo receivers when people don't turn the volume off before starting them and then play a song, turn it on, and let it kick on full blast, but I have always turned my volume on my amp all the way off before turning it on/off. It hasn't been subject to any blasts and is plugged into surge protectors nor do I just unplug a cable when it is on.

    Any advice?

    I had similar volume issues on my CMD 121p. Also heard of a lot of members here with the same.

    All my attempts to repair were dead ends or $400+. I ended up dropping a new LMIII in to replace it. Very easy swap.

    Happy to provide more info if you’re interested.

  3. I had this problem and my CMD121P needed a new preamp board. It also had fractured solder joints on the speaker output connectors. You could remove the combo head and take a careful look inside for mechanical faults such as poorly soldered joints on the speaker output connectors or loose ribbon cable connectors.

    Thank you for the response man! I figured it was a head issue like I have had with receivers doing similar BS, cause sometimes it comes back, but still not full tilt like it was.

    Is there a reason you bought a head @ $650 versus another amp CMD 102p @ $750 and used the new one to just power both via output?

    I already had the 12” extension, leaving me with a headless combo and a cabinet. I seriously considered a different head to power them. Something cheaper, most likely would have been a Peavey Minimax

    But I really like the form factor of the combo, I use that alone most of the time. an open box on a Little Mark III from GC for $475 out the door with warranty sealed the deal. (At the time the LMIII was on sale for $499, but looks like they’re back up.)

    If you dont yet have an extension, and want to stick with Markbass- your “new combo” idea sounds totally viable and cost effective.

    Amazing insight man. I do not have an extension currently and was looking at getting one to gig with until this happened so I may just go that route, but the knowledge that the head caused this is invaluable. Can't thank you enough.

    You bet. Two things come to mind:

    1) you could try running a patch cable from the FX send to the FX return, and see if the volume issue goes away. IDK what this “means” in terms of diagnosis; but I read that here on TB and my local tech even suggested that. I think I could perceive a difference when I tried it; but in the end I felt like I couldn’t trust the head anymore and just wanted to replace it.

    2) if you do take the head out, you’ll be left with a speaker with a male plug end. You could easily convert it to a permanent cabinet with the female end and plate (I think my tech quoted me 20 bucks to do this) or get a female-to-male speaker cable. I even know another guy in town that has the same CMD combo with the same dead head, and now runs it with a GK head. (Can’t remember his connection solution though)… my point is it’s definitely an option as a stand alone cab, with a few different routes to get there.

  8. Just Google "male to female speaker connector/cable". There are plenty of good quality adaptors and cables that mean you won't need to mess with the combo connector.
