ripface Posted April 10 Share Posted April 10 Hi All, I've owned and been using a Line 6 Spider 112 combo for some time and really like the amp. I recently bought a Line 6 foot pedal to use with the amp but it appears the FBV2 pedal I bought is not compatible. That's bad enough, but after trying the pedal out with the Spider 112 the amp is now having problems in that whenever I plug my guitar in I get horrible humming from the speaker with crackling in the background. I can still hear the guitar but this has rendered the amp useless. I presume that plugging the incompatible pedal in has caused the issue as it manifested just after I tried it. Anyone know what the problem might be? Hoping it's not too serious and that it can be fixed? Cheers, Ripface Quote Link to comment Share on other sites More sharing options...
psarkissian Posted April 10 Share Posted April 10 Either an amp IC failed, or an intermittent solder point on the processor board (crackling being digital noise). Find an authorized service center and have them check it out. https://line6.com/find/service_center/ 1 Quote Link to comment Share on other sites More sharing options...
ripface Posted April 11 Author Share Posted April 11 Hi, I pulled the main board and found a blown cap on the PCB. Presume this is the issue, it's a 50v 1pF capacitor. Hoping against hope I can replace the blown cap and get the beast working again!! Cheers, Ripface Quote Link to comment Share on other sites More sharing options...
psarkissian Posted April 12 Share Posted April 12 Make certain the board is cleaned. Capacitor electrolyte is conductive, can short out other components. Quote Link to comment Share on other sites More sharing options...
