@Andy - These are the Dream 180s and unfortunately I haven't heard them yet. All I had to convince me for purchase was the video on the guitarfetish site.

Having said this, I *have* used GFS pickups on two previous builds - my 12 string 335, and my hollowbody 175. For these I used the Retrotron Surf-90s and Retrotron Nashvilles respectively. To my ear at least, these pickups sound freakin awesome! It all depends what you are looking for I guess, but I really love the Retrotrons and their vintage / gretschy sound. I would not hesitate to recommend them to anyone.
That's why I went back for the Dream 180s for this build, because and I wanted to see if I liked others in the range. I'm fully expecting them to sound awesome!!
cheers,
Gav.
