sounds amazing. got it for super cheap. played it at a store and when i got home and played it I was cutting in and out. when i put my cable in it wiggles around cutting out the sound. should be simple to fix. should i just tighten something down?

Open the control cavity in the back, make sure there are no loose wire connections, hold the jack from behind and tighten the nut.

While you have it open it couldn't hurt to inspect the whole wiring set up and make sure the nuts on the pots are tight.

If the socket itself is moving, unscrew the input jack plate, hold the inside of the socket and tighten the nut.

If it's not that, while the socket is out of the guitar, plug in your cable and see if the 1/4" jack makes full contact within the socket.
