time to clear out my old gear. no idea what its worth

Hello, I'm new to the forum. I have some old gear that I have no idea what its worth. I don't want to bring it to one of the local big-box retailers and get ripped off. Any suggestions would be great.

Check ebay, Reverb, Craigslist and the TalkBass classifieds for past sales. There a TB rule that you can't ask for the value of your equipment unless you're a supporting member (I think).
