I was playing earlier today with my gnx3000 and a practice amp and the sound just cut out. I tried everything i could think of and it still didnt work. I had my friend bring his guitar over and it worked just fine, so I determined that the problem was my input jack. Is there anything i can do to fix this or am I going to need to take it into a shop?
Check the soldering on it, I have had to re-solder mine many times.
