In 2005 we created a very handy tool that simplifies the task of transposing (changing) the key of any piece of music to make it easier for a guitar player/singer to always play and sing in their favorite key. We have sold hundreds of copies of our transposer on eBay, and we have recently developed a website to allow customers to buy direct. Retail and wholesale customers are both welcome at our website. Every month the first 10 retail customers to buy the Guitar Player's Friend transposition tool will get a refund of the shipping charge. Our website www.guitarplayersfriend.com also carries a complete line of guitars from entry level to professional level thanks to our affiliation with Amazon.com.
