Hello, I am new to these forums so I apologize in advance for potential misunderstandings :D Yesterday I bought this new Line 6 Spider Classic 15 watt amplifier along with brand new Epiphone SG and a brand new cable. When I plugged the guitar to the amplifier, everything was tippy toppy great, but that's when the trouble started .. I messed a little with knobs and channels but I did not save anything (I did not press the channel button to take a ''snap'' of the tone) and now I don't have distortion and the volume is way down whatever I do. Clean channel is normal, although the volume is lowered.. Crunch channel has no distortion at all and as I move on to Metal and Insane channels, sound remains clean, only it gets muddier .. When I strum, sound is just muddy, no distortion present .. I implore you all for help, since I've waited for this moment for 5 bloody years :D and now I can't get the distortion even a little bit ..Rest of the effects are in working order, I've tested them, tuner doesn't register string plucking at all.. I've tried factory restarting (holding clean button while turning on .. I hold it, the lights above channels blink 3 times and that's it ...still the same) .. I've read the manuals but there's no mention of this problem.. Thank you in advance for any help..
