cheddatom Posted May 12, 2015 Posted May 12, 2015 (edited) [size=4][font=arial, sans-serif]My mate's Yamaha acoustic keeps cutting out. When you pull the jack out and plug it back in, it's fine again. When it happens appears totally random. So far we've tried replacing the socket, and changing jack leads. Anyone got any ideas?[/font][/size] Edited May 12, 2015 by cheddatom Quote
cheddatom Posted May 12, 2015 Author Posted May 12, 2015 Sorry, I tried to sort out the text, has it worked? Earthing... well, all wires are connected up, and it's a new jack socket. When it cuts out, it doesn't go to a buzz or anything like that, it just cuts out. What should we be looking for with regard to earthing? Quote
RAY AGAINST THE MACHINE Posted May 12, 2015 Posted May 12, 2015 If it's an active guitar , it could be the circuit board. Possibly a wire has broken inside , if it's actove Quote
cheddatom Posted May 12, 2015 Author Posted May 12, 2015 it is active, yes, but the circuit board is nowhere near the jack socket, it's on the upper shoulder (which I think is standard?) so I wouldn't have thought a dodgy connection on the pre-amp would be doing it, is that what you meant? I know turning computers off and on often fixes them, but an analogue pre-amp?! Weird! Quote
KK Jale Posted May 12, 2015 Posted May 12, 2015 Retensioning the battery snap would be my next port of call. Quote
cheddatom Posted May 13, 2015 Author Posted May 13, 2015 If it were a dodgy battery connector, would unplugging and re-plugging the jack cable make any difference? As this does fix this problem Quote

[/quote] Reason o mentioned it , was that the problem sounds exactly like had with my Washburn status.T he only difference being you haven't received police radio or French radio stations like I did Quote
cheddatom Posted May 14, 2015 Author Posted May 14, 2015 no, no interference or noise of any sort, the preamp is great, it just cuts out randomly. It can be fine for weeks, then it suddenly goes silent. Take the cable out, put it back in, and it works again It'd be OK except if you do that in the middle of a song without telling the soundman he doesn't like it Quote
tauzero Posted May 14, 2015 Posted May 14, 2015 Does just turning the jack plug in the socket revive it? Quote
cheddatom Posted May 15, 2015 Author Posted May 15, 2015 Not as far as I know. I don't have access to it at the moment but will check it out on Saturday. I have tried all manner of jack waggling but turning didn't occur to me! Quote
gelfin Posted May 17, 2015 Posted May 17, 2015 Just had a similar problem with my mates electro acoust ic 12 string. (last night) Turned out to be the jack socket. the part of the socket that connected to the sleeve of the jack plug had bent a little with use, over time. On close examination it was not touching the sleeve but just resting on the insulator between tip and sleeve. Quote
cheddatom Posted May 18, 2015 Author Posted May 18, 2015 well he replaced the socket for the 3rd time at the weekend, all seemed well, then it happened again during the first song of our set. The pre-amp was replaced about a year ago, and the problem was happening before and continues (it was replaced due to a snapped pot shaft, you can't get them individually) I did suspect the jack cables he had might not fight the socket correctly, but we've tried every combination now So, absolutely stumped. The only electronic parts that haven't been touched are the battery compartment and the pickup.Once it cuts out, you take the jack and, put it back in, and it works straight away. If it was an intermittent fault on the battery compartment, then you'd have to move something close to the battery compartment in order for it to start working again I'm so baffled Quote
RAY AGAINST THE MACHINE Posted May 18, 2015 Posted May 18, 2015 Maybe, ( but I doubt if it will work ) - your guitar cables.Have you got a cable that's flat at each end? Try that , especially if sitting down while playing . If not , sell it on flea bay Quote
cheddatom Posted May 18, 2015 Author Posted May 18, 2015 Flat at each end?! I've never seen a flat guitar cable? Quote
RAY AGAINST THE MACHINE Posted May 18, 2015 Posted May 18, 2015 Can't do pics right now, but I've probably not explained properly. I think they call them right angle or something . ( I'm working right now). Basically your guitar cable will fit flush in the jack. Rather than stick out . If nobody beats me to it, I'll put pic up later;) Quote
cheddatom Posted May 18, 2015 Author Posted May 18, 2015 ok, yeh, I have one of those, I'll get him to try it, thanks! Quote
cheddatom Posted May 19, 2015 Author Posted May 19, 2015 we tried it last night and it didn't cut out once. This doesn't necessarily mean it's fixed, but another few rehearsals and gigs with this cable would convince me. So what's the explanation? The jack just goes into the socket a little further? Quote
squire5 Posted May 19, 2015 Posted May 19, 2015 Just a random thought,and probably miles off.Could the trouble be at the other end of the cable?Is it always plugged into the same input on the amp/desk.Could there be a fault there?Give it a wiggle down there next time,or try another input.The angled jack could be just coincidence.Like I said,probably miles off,but hey.... Quote
cheddatom Posted May 19, 2015 Author Posted May 19, 2015 The other end goes into something different every week. Amps, DI boxes, straight into the desk etc. I'm pretty sure it's not that end as when we un-plug and re-plug it works, and this is only done at the guitar end Quote

[/quote] I had a jack problem( same as yours), with my steinberger. It was fixed eventually . Then, one day , while playing sitting down, I realised the lead was sticking out. I got a different lead, same as dads above - problem solved. Quote
cheddatom Posted May 19, 2015 Author Posted May 19, 2015 This is so weird. He must have tried pushing the jack in once it had cut out, and that would have solved it... Maybe not! Well, anyway, if it's solved I'm happy. Thanks for all the help Quote
Dad3353 Posted May 19, 2015 Posted May 19, 2015 We've all assumed (I presume..?) that the jack lead is looped through the strap to take strain off the socket, but even then, a 'straight' jack can work its way loose, just by the weight of cable. The right-angled jacks solve this, for the most part, and I would recommend 'em for all except 'strat'-type jack plates. I have the same at the amp end, too, which reduces the risk of the jack being pulled out. That may not be the cause of your worries, but it won't harm to adopt angled jacks, anyway. There's not much downside. My cables were made by our OBBM expert, so will last at least my lifetime. Quote
cheddatom Posted May 19, 2015 Author Posted May 19, 2015 yes he does loop it round his strap I've always used straight jacks with my basses, which have the same stereo barrel type jack as in his yamaha acoustic. I've never experienced anything like this! Anyway, I'll give it a few gigs (3 this weekend!) and then report back Quote
