I get LOADS of feedback on my RG7321..but if u put my thumb on the jack it goes away?? wtf?
I'd be happier to blame the rest of your setup tbh.
it could be to things.....a lose jack socket as in the cable is touching the shielding in the jack so just tighten it up OR you cable is broken (a lose wire maybe) so try it with a different cable if you get the same problem its your jack.....
Well i get no feedback with my Dean
maybe your doing all this in front of your amp?
try a different cable?
hmm idk then
I did its no different and like i said its fine on my Dean using the same cables
Check the solder/connections and re-solder, specially the ones to and from the output jack.
I have NO idea how to do that
