A few days ago I bought a line six spider II 112 combo. The first time I turned it on to play, it sounded great. then i turned it off to go eat dinner. after i came back about 45 minutes later I tried to turn it on and it did nothing, I checked to see if it was plugged in to the wall, and to the amp and allthe other stuff that your supposed to check first It still wouldn't work. If anyone knows what could be wrong reply to this.
Did you check if your guitar was plugged in?
did the lights on the amp come on when you turned the amp on? if so maybe check the volume on your guitar.
mine did the same thing a few days after i bought it so i just brought it back to daddys junky music. its covered under manufacturer warranty most likely if nothing turns on its the power unit, thats what the guy told me it was when i brought mine back.
