I have been a large dealer for a lot of companies. I have been given 5 or 6 PRS guitars for free. Kramer gave me a spectacular Stagemaster for Xmas one year. Steinberger gave me 6 guitars as severance pay in 1990 when I worked as their artist relations and domestic sales manager. I could go on but you would only hate me more.
Nobody can sell a guitar better than someone who personally owns one can.
Besides it's human nature for someone not to off-sell a company that gave him or her a free guitar. The point I am getting to is this. In 25 years of buying, selling and trading thousands of new and used guitars. Except for one exception. I bought my Parker at full dealer price.
