cheddatom Posted May 29, 2015 Author Share Posted May 29, 2015 well, it was worse than ever and he's resigned himself to buying a new guitar. Everyone I've asked about it is totally baffled Quote Link to comment Share on other sites More sharing options...
Count Bassy Posted June 1, 2015 Share Posted June 1, 2015 Has he changed the battery? I had a problem with my GWB35 and tried everything, including the battery connector, but it turned out that there was an internal fault in the (Duracell) battery. It was really really sensitive and unplugging and re plugging the jack socket was often enough to make it go again - for 10 minutes or so. However when that went on and off it did so with a big pop, but I guess that that will depend on the pre-amp design. Quote Link to comment Share on other sites More sharing options...
cheddatom Posted June 2, 2015 Author Share Posted June 2, 2015 I'm sure he's changed the battery a few times. The only "pop" is the noise when he plugs the jack back in Quote Link to comment Share on other sites More sharing options...
Les Posted June 2, 2015 Share Posted June 2, 2015 Do the jack socket and piezo connect to the preamp by mini jacks ? If so have you checked these are in properly ? You can generally get to these through the sound hole. Quote Link to comment Share on other sites More sharing options...
cheddatom Posted June 4, 2015 Author Share Posted June 4, 2015 Not sure, i'll pass that on Thanks for everyone's help on this! Quote Link to comment Share on other sites More sharing options...
PaulWarning Posted August 30, 2023 Share Posted August 30, 2023 @cheddatomdid you ever find a cure, my electro acoustic started cutting out about once every song at a recent gig, if I pressed the tuner button it connects again, just tried it now it seems ok, but I don't trust it Quote Link to comment Share on other sites More sharing options...
cheddatom Posted August 31, 2023 Author Share Posted August 31, 2023 Hi Paul, no, he swapped the guitar in the end. Maybe there are some sort of ICs on these pre-amps that need a reboot every so often, like a computer, but I doubt it as no-one mentioned it on this thread The guitar he swapped to is another Yamaha, a very similar model, and he's never had an issue with it once! 1 Quote Link to comment Share on other sites More sharing options...

sandy_r Posted September 2, 2023 Share Posted September 2, 2023 Just throwing in an idea from left-field here: some battery-operated electronics (incl. tuners) have timers to power-off the function if not operated for a certain time, to save battery. IF (yes, it's a big if!) a fault develops in the function switching logic, or power-switching components, then I guess this reported behaviour (random cut-out) could be one possible fault-mode Unplugging/re-plugging the jack will power-cycle the electronics, and therefore, in effect, provide a 'reboot', as mentioned in prev posts 1 Quote Link to comment Share on other sites More sharing options...
