gsmccoy Posted November 7, 2018 Share Posted November 7, 2018 Been using this guitar without problems for several years. Now suddenly, it will not power up with an external power supply. It works okay with the battery. I have tried two different JTV power supplies (both the switching unit and the DC power units), and I have tried to power it with my old HD500, using the Variax cable. None of these will power the guitar. I am stuck with the battery, which is ok, but having no back-up leaves me vulnerable. I have tried this: I inserted a 1/4" plug into the guitar and turned it on with battery power. Guitar comes on. As soon as I plug the other end of the cable into the JTV power supply, the guitar shuts off. Any suggestions? Quote Link to comment Share on other sites More sharing options...
psarkissian Posted November 7, 2018 Share Posted November 7, 2018 Does the guitar cable have TRS (tip/ring/sleeve) connector ends? Also, being an older guitar in the bunch, it may need the guitar equivalent of a 50,000 mile check up. Quote Link to comment Share on other sites More sharing options...

I have tried several, in order to eliminate cable failure. 1 hour ago, psarkissian said: Also, being an older guitar in the bunch, it may need the guitar equivalent of a 50,000 mile check up. I'm afraid this is a probability. 1 hour ago, psarkissian said: Quote Link to comment Share on other sites More sharing options...
