So I was wanting to play my crappy Yamaha Pacifica. I plugged it into my 120 watt Line 6 Spider II, and started to play. Absolutely no sound came from it. I checked all my settings, and I know it should've been playing. Anything else I should look at? My friend said it might be my input.
Yeah sounds like one of the wires for the input jack has come lose. It's a quick 'n' easy solder job, the kind you can do yourself. If you're not sure about it take it to a pro and they'll fix it pretty cheap. If it is the input, keep the nut on the jack nice and tight and it won't happen again.
you tried plugging your guitar into another amp? another guitar into your amp?
and swapping out the guitar cable.
checking your volume on your guitar?..........its an easy thing to forget about
cables can also break, just another thing u might wanna check
