this should be of interest to many amongst us here : I have recently bought a rather rare vintage Plectrum Banjo off ebay, from a music store in Seattle. While searching for info online I found a photo of such an instrument on this VERY useful site : https://www.gear-track.com/ and BINGO - to my unpleasant surprise I had to realize that the instrument I had bought was reported as stolen in Tacoma/Wa in January 2014. I could have kept quiet but the bad karma that would have come from playing an instrument that was not rightfully mine made me act accordingly and I contacted the owner via that site. The seller agreed to take it back and hand it over to the rightful owner and to investigate the source where he himself got the instrument from. I will certainly register my gear with that site and urge all of you to do the same and PLEASE take the extra precaution when buying gear to make sure that it's not hot property. there is too much stolen gear going around and not enough people care. Thanks !
