![]() To avoid that battery being constantly connected to the preamp, draining the battey when you're not using the guitar, the ground side of the power supply circuit is usually run into the jack using the "ring" contact of a tip-ring-sleeve or TRS jack in the instrument. To what end, I can't say, but I can say that the change in cable is significant and is the primary reason for your woes.Īcoustic-electric guitars have a battery-powered preamp. Your sound engy is hacking the guitar's connection to the mixer. Sorry for the barbaric language, it must be painful to read but I really need help. My guess is to test connectivity between the undersaddle pickup ant the output jack and then start to narrow it down, is that right? Now for the win, the thing I asume I need to do first is to test connectivity between all parts of the electronic since from the symptoms it would appear that either the pickup is not getting the signal to the preamp or that the circuit in the preamp is fried. Is it ok any of the three or do I need an specific one? I guess I could get bad sound from it but not no sound at all.So, if I get a replacement, Ive seen three different types, mine is like a braided thick cord, Ive seen a flat, thin, usually red coloured type and the third are like made of metal. Today I pulled the strings and pulled out the undersaddle pickup to take a look, it is in very bad shape. It is the main reason why I do not think is totally a cable/plug thing, I think there is something really wrong in the whole electronics. Long before all the onboard tuner of the Fishman Presys started acting out, and stopped working. The question is: do I need in general a TS-TS cable or it shouldnt matter if I have a TRS-TS for example? I noticed that because today a different guitarrist brought his Epi that used to work as well and spent 1 hour trying several things until he slightly pulled the plug and achieved sound. The cable we used to work with was a TS (guitar) -XLR (console), now they are using a TRS (guitar) - XLR (console). Here are a couple of things I would like your ideas on: I dont really have a chance to test it anywhere else. When asked the audio guy he plugged a different (and cheaper) guitar and it did work, thus telling me to fix mine. Since they changed the cable "asigned" for guitars it doesnt amplify at all. I have a cheap Fender guitar that use to play at Church. From previous experience I know you are a source for good advices. ![]()
