I have a 1981 G&L L-2000E. I am considering selling it. I have some questions regarding it. First off, I am curious to know whether or not the "Patent Pending" that is on the headstock and bridge has any significant determination as to its value. I also was told a (long) while ago that Leo Fender used to sign certain intruments on the neck heel. I took the neck off once in the 28 years that I have had the bass to see and it does appear that there is some type of intials on the heel of the neck. If there is any truth to this, I would love to know before I begin the process of selling it. Thank you.
