The plug jack on Ibanez Ergodyne's are garbage! For one they are plastic. Not unusual but this is really cheap plastic. Secondly the nut for the jack constantly comes loose so you have to take it apart and tighten it. Thirdly this causes the wires inside to twist and eventually break from their soldering. This weekend will be the third time since last February when I bought it new that I will have to resolder the wires and try to tighten the cover. I would tighten the cheap a*% cover as tight as I could if it wasn't plastic. I'm afraid I'll crack it in half. After I do this I'll probably put the piece of #@$! straight out on E-bay. Ibanez's are for beginners that don't know anything about basses yet. That was me last March. Never again. Oh yeah by the way, the fretboard and the tuning pegs suck too. I should have burned my $550!!! The $290 dollar soundgear I had first was actually built better!
