an Ibanez GSR190 beginner's bass. Played okay, but the pickups sounded like mud and the tone button could just as well have been a knob not connected to anything.
If basses don't count, my CIJ HH sunburst Jag. It was like 3rd hand, but the second owner didn't play guitar, was a bassist (had like 4 different ones that were all reaaaally cool) It didn't have any major scratches on the front and played awesome, so I went for it.
