Got a set of medium scale golds from Jason for Christmas and just put them on my 32" J fretless (w/ Nordy dual coil pups) and it's the best that fretless has ever played and sounded. I tried the white tapewounds when they came out and liked them, then the coppers and liked them too, but these definitely sound the best. Nice punchy mids, full but clear bottom and just the right amount of fretless "mwah". The coppers were a little woodier sounding and more "polite", but these have some nice growl to them and can get more aggressive if desired. I went with the standard gauge set this time and I think that helped too.
