Good Humbucker at a Fair Price in Electric Guitars Posted September 25, 2015 I listened to a a few You Tube videos that compared GFS with Dimarzio and Duncan and you can real tell the difference. THe Duncans and Dimarzios just sounded better. So I think I am going to bite the bullet and get a Duncan Custom Custom or a Dimarzio 36th Anniversary. Those sounded the best. I was almost going to get a Duncan JB because that is the most highly rated and reveiwed humbucker on the music store websites, but in a video someone put it up against the Custom Custom in the same guitar and it sounded like Mud. The Custom Custom sounded way better to my ears.
