    Tube problem would be my guess.

    I think so too, but in another group page some said that it could also possibly be a cable issue. Plugged the guitar straight into the amp and didn't experience the issue. But after trying it with another guitar it sounds super mega microphonic. I will be doing more in depth troubleshooting tomorrow after weight lifting so hopefully it gets resolved

    Do you have any electronic cleaner like Deoxit? I'd start by cleaning all your tube sockets and reseating your tubes. Clean all your inputs and pots too. Clean all your pedal inputs too and guitar inputs. If its still a problem you might have a bad tube, test all your tube positions with a known good tube.

    Have you tried your spare tubes?
    Have you tried direct in with no FX?
    Have you tried with a different guitar?
    Also try direct into the FX return (will be loud)...
    Have you cleaned all the jacks?

    Sounds like arcing JJ power tubes. My DSL 50 did this a while back. Drove me nuts thinking it was a bad cord or connection. It eventually popped a fuse and I took it to the shop. The shop was really cool and didn't even charge me for the service. He turned it on and saw the power tubes arcing.

    What is this "arcing"? What do I have to check to see if this is the issue I am having

    I plugged it in direct and no issues.

    I tried a different guitar (not plugging it in directly) and same issues on that guitar aswell

    Did not try direct into the FX.

    I will clean the jacks

    Turn the amp around. Look for sparks flying inside the power tubes as you're playing and the amp is cutting out.

    Question : does the amp cut out when you plug the guitar straight in no pedals ?

    Does the amp cut out with a different guitar ?

    If yes to both try a different instrument cable.

    Jiggle the input jack if possible to see if its loose.

    "Arcing", what he said. Sparks or tiny lightning bolts inside of power tubes. If you see it, then power down immediately and get new tubes. This can also cause more damage if let to continue.

    It is now doing it when I plug it in directly..... I unplugged everything from the amp and only had the power cable in and i started lightly tapping the backboard of the amp and it started making that scratching sound so I am at a loss here

    Have you tried new finals?
    Make sure you bias it after replacing them...

    Power tubes. The final section of the amp.
    Sorry, old term used by us radio nuts...

    Put in your spare set and bias it up to see if it still does it.

    Like others have already said, just retube the whole amp...that more than likely what is causing the issue. Preamp tubes are cheap and stock Marshall ones are not that good IMO. While in the amp, check to make sure all the connectors are well seated and tight, clean all jacks and hopefully you should be good to go.

    Hey thanks for the responses. I do not have a spare set of Preamp tubes. I also do not really plan on keeping my DSL much longer since I am saving up for a Kemper. Is there any way that buying another set of preamp tubes will fix this issue?

    If the issue is in a pre-amp tube then yes. If its in the power tubes then no.

    How can I determine if it is a pre-amp tube? Will I just have to buy a new set, swap old with new and find out from there?

    I originally thought it was a cable issue since that seems like that would be an issue that could be viable. When I heard that same crackling weird sound when NOTHING was plugged in I new that it was something more than that so that raised a bit of concern for me last night when I was doing some troubleshooting
