    How the hell to open my Marshall MG15 FX?!

    So I have my little Marshall practice amp that I love, but the little plastic washer that holds the input jack came loose and the damn jack fell inside in the amp! So I read online one thing that said how to open it up so I could fix it, but I unscrewed everything and nothing comes out. The back panel is still on there is no way to get a hold of it to open it and the front panel, I have no idea how to begin to get leverage to even pull it out if that's what's supposed to happen! I really don't want to have to go an amp shop to fix this. Does anyone have any clue how to get one of these open?

    I've never had that issue before , Brett . Hope you get it figured out with minimal headaches ...

    It's maybe a good time to make a note of preventative care for our guitars/amps/equipment ? Stuff like jacks (like you described) should be inspected and tightened every once in a while . Same goes for stuff like strap buttons , tuning keys , volume pots , toggle switches , etc. Pedals and other gear too .

    Repeated use causes stuff to wiggle loose over time .
    A lot of little things get overlooked , and I'm guilty of it too , but it's a good idea to try and make a habit of checking those possible trouble spots .

    It is hard to visualize what you described, maybe if you were able to post some pics. I believe you should be able open the back of the box, disconnect the speaker, remove the screws from the top and take the amp out from the rear.

    It may have preserved into a form of driftwood now. Imagine how cool that would be?

    1. Take off the back panel.
    2. There are 4 screws on top of the amp.
    They hold the chassis with the electronics of the amp securely to the the top of the wood frame.
    3. Unscrew them and you'll feel the chassis start to get loose.
    4. Pull the chassis out from the back.
    5. Find the input jack and reconnect it to the chassis.
    6. Put it all back together again.

    Actually there were 5 screws on the top. Ok so the back is all unscrewed how the hell does it come off? It doesn't just fall off and I can't wedge anything in there to pry it off. Click image for larger version.

    I can see from your pic that you have a slightly different version than mine. The panel on yours covers the entire back...mine is 3/4 covered. The chassis on my mg15 slides out. I assumed our amps we're similar, sorry about that. But glad you managed to fix it.

    Good point!
    I can attest to making sure the jack nuts are tight...especially on combos.
    My problem was the jack nut had come loose on my Vox (control panel on top), and my cord got stepped on, and it tweaked the jack over. Problem is, is the jack is soldered directly to the board, so the board also cracked when it broke free.
    I had to open it up, repair the crack with epoxy, bridge it with wire and resolder the jack, and like Brett's, it's a bear getting those amps apart.

    The same thing happened to my friend's Randall combo, and again, it was soldered direct to the board.
    I't was much easier to fix his....Just broke the connection, but I went a step further, because there was enough room to replace the jack with a different style, and I wired it to the old connections.
    That way, if it ever did get pulled again, it stood less chance of cracking the board like I did on mine.
    In both cases, if we both had just kept an eye on the jack nuts which are usually plastic nowadays, it wouldn't have happened....but if manufacturerer didn't chince out, and they were actually metal with lock washers, it wouldn't have happened in the first place.
    Vibration will always loosen smooth plastic parts on combos.
