OldJenkins Posted February 5, 2018 Share Posted February 5, 2018 Hi, Today I got a problem with my Spider Classic 15. I was playing with my cellphone connected to it via jack on the CD-MP3 input. Then a friend tried connecting it to a laptop via the same connector, and the amplifier started hissing heavily. If I touch with my fingers the end of the jack the noise is lower, but its still there. If I do this and at the same time I touch the strings of the guitar it dissapears. If someone is holding the end of the jack while I'm playing it sounds perfect, but I don't know why, and what to do to repair it. Someone has any idea of what happened and what should I do?

fflbrgst Posted February 5, 2018 Share Posted February 5, 2018 So this hissing happens all the time now? Have you tried plugging your phone in again to the MP3 input? Quote Link to comment Share on other sites More sharing options...

Yes, I tried connecting it again, but it keeps hissing. Also, if I disconnect the guitar cable from the amplifier there isn't any noise, and if I play music from my cellphone plugged in the amp it sounds perfect. Can't figure out what is it. And if the guitar is disconnected from the amp and I touch the end of the cable it starts making noise. Quote Link to comment Share on other sites More sharing options...
fflbrgst Posted February 6, 2018 Share Posted February 6, 2018 Have you tried a different guitar cable? If that doesn't change anything, then there is some problem on the input side of the amp. Unfortunately, the Spider 15's are not field serviceable. If its still under warranty, you can bring it back to where you bought it or exchange.
