Hope this is ok here couldn't see a troubleshooting forum.
You could say I'm a newbie which explains my naivety in this area.
Had this Jack Casady couple of years now and a fender rumble 75 about three. Just like learning riffs at home so nothing serious. Anyway, kit was fine the other day until I had a break, then when I came back to it literally 5 mins later I couldn't get any guitar out of the amp only really loud buzzing even at relatively low volume settings. So I thought lead. Tried another lead, still the same. Tried the Ibanez AE8, nothing. Tried an ampjack, still the same, nothing no buzzing though. So removed the Epiphone's jack socket and all appeared good.
That's where I'm stumped. How can it be the amp when it's the same with the ampjack? How can it be the guitar when it's the same with another?
Can anyone help? Preferably from experience.
Cheers.
