How to fix channel 2 not working on Marshall AS100D amp

I got a Marshall AS100D from my friend Gary who plays in Avian Aura. He stated that Channel 2 no longer worked at all. This video shows you how to take the Marshall AS100D apart in order to diagnose the problem. Then I show you how I fixed this particular amp with a super simple cleaning process.

Wow nice work! Mine had this exact problem. After I watched your video I tried repeatedly pushing in those buttons and suddenly it started working. Didn’t have to take it apart. You saved me a lot of time!

Great to hear!

Excellent video. I have a gig this weekend and that channel was dead and your tip fixed it perfectly. Thank you!

[@scottaumann]

[@scottaumann]

Glad I could help

[@brentmacphee872]

Thanks Man! Just fixed mine and I didn't even take it apart. I just sprayed contact cleaner in after pulling the knob off!

[@scottaumann]

Nice work!

[@billybsings]

Amazing ! I have the exact unit with the exact same problem. I could do what you have done, but I might try squirting in from the outside first, with multiple clicks. Thanks so much ! Now I just have budget the time.

[@scottaumann]

I hope you can get yours to work also. It is worth a try going through the front. I wouldn’t spray too much cleaner as it gets messy fast. A little goes a long way. Good luck and let me know if you get it to work.

[@billybsings]

@@scottaumann will do, and thanks again

[@stephenrichardson3999]

I tried going from the front first but it is sealed plastic except for where he showed the opening... you'll likely need to take it apart as shown in the video.

[@billybsings]

@@stephenrichardson3999 Still haven't tried yet, but I will keep you posted, probably within a week

[@AndreRoseBuenoTravel]

Your video was very helpful to see how it can be opened and even some issues resolved. But I don't know if will work on my case. I think someone used the speaker and overdrive a lot, because when I use now is giving me this sound of deeper down overdrive or loosing thing inside the sound as I said before.

[@scottaumann]

Hard to say without hearing it in person. It might be a blown speaker. You could try sending a signal out of the amp to another device to see if the distortion continues. If so, then the problem is probably happening on the input side of the signal chain. Good luck!

[@AndreRoseBuenoTravel]

Hi Dear my Marshall AS100D is giving me some distortion on the sound even if I turn the effects out as it sounds distorted overloaded or battery low. Does this amp has a reverb chamber like some old models where they have a coils to produce the reverb or this model is different? If you understand what I mean.

[@scottaumann]

I believe this model has only digital effects. No reverb tank as far as I remember.
