I have one. It is an OK pick up IMO. Pretty clear highs & pretty strong lows. As someone else mentioned, it seems to lack much midrange. It was replaced with a Keystone. I love the neck pickup. I've replaced the Keystone bridge pup though. The GFS will cost around $39 shipped. I would do a little more research and see what may make sense. I highly recommend the Keystone neck pup. Very clear and punchy...zero mud. I think you have to buy them in sets but you can easily sell the bridge pup as these are pretty popular pickups. You'd be in for less than the GFS.
