    Hi, I'm writing this post because heard I'm not the only one to have a guitar that sometimes "switches off" while playing. Do you have a view on this? Does your G400 do this while you are playing it?
    The lastest time it happened was yesterday night. The guitar usually have problems with the rhythm pick-up, but yesterday it happened to the treble one. I thought the problem was getting bigger, so I opened it. The electronic circuit seems to be ok, I do not see disconnected wires or broken ones or similar. Can you give me an advice?

    With "guitar switching off" I mean that while I'm playing for a short period of time the sound seems to fall to ground, so you do not hear anything. I'm not the only one that noticed it, so for this reason I want to ask you if there is something I can do.

    Given your symptoms, the most likely culprit is the pickup selector switch. This is one area where Epiphone have gone a bit too cheap. Replace it with a decent one (Switchcraft?), which you can get from Stewmac.

    Or first give the underside of the switch a spray of electrical contact cleaner and work it back and forth a bit. Might solve the issue cheaply.

    It could be an problem with the wiring too, even if you can't see anything wrong. You can use a multimeter to find any bad connections.

    This is probably your best shot.

    If you want to go a step further, take it out, take it apart, bend the prongs a tad towards the middle so they put a little more pressure on the lever, reassemble, lubricate and voilà. You're good to go for a few years.

    I lubricate my 4 Epiphone toggle switches about once a year and even the 17 year old SG still perform flawlessly.

    It's probably the switch as others have said, but I believe it might be a box type switch. Simple fix is to spray contact cleaner, or lacking that, WD40, into the hole, and wiggle it like crazy for 10 seconds. Should fix the issue.

    Thank you to all. I love my Epi and I don't want to separate. I'd like to keep it the most original possible: I love it as it is...

    You are right, I thought the same thing. I usually resolve the problem switching from treble to rhythm and viceverse quickly, so I think the real problem is the switch, not much the wires, but have a checkup is always a good thing.


    Thank you again!!! :bowdown:

    I'd like to ask Tony Iommy if he uses his SGs for other genres, eheh... :rofl:
    Well, Epiphone and Gibson SGs are good for blues, rock and metal. I use my G400 for songs from blues to hard rock, then there's the cousin Gibson for stronger music. I don't mean that the Epi doesn't play Sabbath (it does and pretty well!). I listen to my heart and to my guitars, I like giving them a specific genre because I know they can do it well, and yes... expecially for AC/DC's music I rock hard. I feel born to play that and I'm proud of it, I don't care if scientists say rock 'n' roll is noise pollution.

    It's clear from your attitude that you can't, and will not, fail. Check out Thundermother from Sweden. https://www.thundermother.com/

    Are you playing your guitar straight into an amp....or do you use effects pedals? Some pedals when used together can sometimes "cancel out" or reduce signal when used in conjunction with other similar type effects pedals.....usually modulation type pedals.

    Looks like an intermittent switch/switch wiring issue. But please just check one more possibility that may have been overlooked.....check the lead from guitar to amp for possible intermittent loss of signal...maybe try another lead if you have one.

    Yes, I have another one, I try. Also one of my friends that has a G400 like mine (I think his is just one year younger, but it's the same model, so I suppose the same harware), has the same problems, so I don't think it's a problem of wires from guitar to amp... I was worried about wires inside the guitar or more serious problems, which could force me to replace some important elements, like the pick-ups. If it's only the switch I can resolve the thing cheaply...

    Coming back, thank you, I check with a different cable.

    It is a very common occurence on Epiphone toggle switches, just clean/lubricate it.

    I hope that you can fix the problem quickly and get back to uninterrupted guitar playing.

    Get a good high quality switch from Gibson...not much of a fan of Stew Mac. If you like to play it's a small cost.
