How do TB members go about research before buying or selling gear. I'd like to know if there are any resources out there I don't know about, or that may be helpful to other forum members. Ultimate goal here is to get together a list of resources to preempt the "What's my bass/pedal/whatever worth?" forum questions. Not that there's anything inherently wrong with asking a forum, but might be good to have a valuation DIY resource guide so that helpful homework can be done first. What I can contribute that could be helpful (and is likely super obvious): For the most useful data- finding data on gear that has actually sold: Searching eBay for Completed and/or Sold listings Using Reverb's Price Guide Searching old TB (or other) Classifieds to see if I can approximate what something sold for Vintage Guitar Magazine's Price Guide (haven't tried it as requires purchasing it, but I know about it) Second best data (asking prices): Checking Sam Ash, Guitar Center, Music Go Round Used listings eBay active listings Using a Search All Craigslist to see what's out there What have you found useful? If we wind up with decent responses, a lot of options, or otherwise plentiful super helpful advice, I'd be happy to compile into some kind of user-friendly format if this thread alone doesn't suffice.
