Im new to this site and this is most likely an old question but is thier a website that you can goto , to longin a serial # to verify that a les paul is a true gibson from gibson and the year it was made and what model it is , a custom standard or traditional because ive seen some guitars that i know they was something not right about the guitar they just wasnt correct . And what reason would someone have not to give you the serial # of a guitar they are trying to sell you . A guy on ebay has a brand new les paul forsale with the in and out phase pots but wont give me the serial # so i can check it out ? Does this sound fishy to you ? Is thier a good reason not to give me the # ?
