Yesterday my brand new Yamaha Revstar RSS20 arrived. Beautiful guitar. Lovely fretwork. Gorgeous finish. 5 minutes of un-amplified noodling told me that the neck is super comfortable and smooth. So I plug it in. No output. Different amp, different lead, nothing. Check the wiring, all looks good, jack is in good shape with no issues. I write an email to Yamaha, and speed my new guitar off to the nearest tech. He takes it into the back and 5 seconds later I hear amplified strumming. He comes out and says "probably just a bad lead, but also the volume knob was turned the whole way down so it might have been that" and I immediately pack it up while saying "YES YES THE LEAD THAT LEAD HAS GIVEN ME PROBLEMS THAT MUST HAVE BEEN IT GOODBYE".

TLDR I AM VERY STUPID
