Squier Precision...been a super great bass, but now its doing this thing to where it'll crackle while Im playing...figiting with the cord going into the input (on bass) temp helps. Itll crackle, then either the volume will go WAY down, or just go dead (no sound at all).

Ive "messed" around with the input jack, squeezing, checking the connections, ect...what could it be? (BTW I tried the cord/amp on another bass and no prob, the prob is def in the bass). Is it time to upgrade my electronics? (BTW again, I love this bass and have done several ugrades already including bridge, p/g, tuners, ect. so I dont mine spending money on this lower end, yet fun and faithful bass

). TIA.
