Hi, I have a B.C Rich body art edition Warlock, it is in desperate need of new strings but I'm unsure of what strings I need to buy! Also, I have an issue with it when I plug the jack in, I only get sound out of the amp when I hold the jack plug at a certain angle near the input on my guitar (if that makes sense!) Any help with both of these questions would be much appreciated! Thanks
I've now bought, Ernie Ball power slinky 11-48 strings, the lead works fine on my fender stratocaster so dont think it's the lead, any ideas people??
Then some wiring is loose inside your guitar. Take it to a guitar shop that has a tech. Its a cheap fix, few bucks at most.
