doc40hz Posted December 2, 2018 Share Posted December 2, 2018 I've got a bass with a mystery crackle (comes and goes all the time). I wonder if its the input jack. I've resoldered the wires as the joints look dry, which has improved things somewhat but the crackle is still there. I ordered a replacment input jack, but it only has anchors for 2 wires. The one on the bass has three wires.... What's going on? Excuse my ignorance! Quote Link to comment Share on other sites More sharing options...

(Which suggests you have active electronics on board as the third pin helps to complete a circuit and essentially switch the circuit on). The type you have received is a mono socket (TS) which would be used on passive instruments such as a standard precision bass. 1 Quote Link to comment Share on other sites More sharing options...
Count Bassy Posted December 3, 2018 Share Posted December 3, 2018 It's an output jack. 2 Quote Link to comment Share on other sites More sharing options...

But that said, Dood answered your question. You need aTip Ring Sleeve (TRS), where the ring functions as a battery on switch so when you pull out the battery disengages.

rmorris Posted December 3, 2018 Share Posted December 3, 2018 wrt the original jack. I' d try cleaning the contacts with Caig DeOxit and then IPA (Isopropyl Alcohol not India Pale Ale 😊. And pushing bending the contacts in a bit. Over time they can lose their tension and not make secure contact with the plug. Quote Link to comment Share on other sites More sharing options...
Adethefade Posted December 6, 2018 Share Posted December 6, 2018 If it's the 'barrel' type jack unit used on lots of active basses then they're all a bit dodgy in my experience; even the expensive ones They have a limited lifespan before they begin to crackle or cut out. As explained below, the TRS (so-called stereo) jack arrangement with three connectors is there to facilitate the battery connection as well as the output signal. I'd get a few spares and keep them handy. Quote Link to comment Share on other sites More sharing options...
prowla Posted December 8, 2018 Share Posted December 8, 2018 I've just fitted a replacement TRS (Tip/Ring/Sleeve) barrel jack to a Warwick; it was n easy job, as it has a solderless connection to the (active) control circuit. If it's an open socket, then Switchcraft are my preferred brand. Sometimes you can fix a loose socket by just pushing in the tangs a bit so they grab the jack plug tighter (but don't overdo it!). (And yes, it is an output socket!) Quote Link to comment Share on other sites More sharing options...

Yes, sorry, it was a bit abrupt. Quote Link to comment Share on other sites More sharing options...
