I got these strings specifially for a Gretsch Broadcaster shortscale (that can't use shortscale strings due to the tail piece).
I had tried several different strings, rounds and flats, on this bass and always felt it was lacking something. I definitely liked it better with flats than rounds but it always sounded a bit muddy. Not that I wanted a brighter sound, just something a bit more focused.
I remembered using these GHS Precision Flatwounds a couple of years back on another bass and ended up preferring other flats that sounded fatter. But I had a feeling the Precision Flats with it's very focused fundementals could be perfect for the Gretsch. And they were!
I'm very happy with these strings on my Gretsch. They may not have the huge, fat sounds of something like LaBellas but the strong, focused fundamentals were perfect for the Gretsch.
Highly recommended if that's the sound you're looking for. They do take some time to break in though. The string to string balance/brightness is pretty poor straight out of the package. But once they break in they sound amazing.
