The tapered wound at the ball end is clearly designed for a bass with separate stop-tailpiece and bridge, à-la Warwick, to quote the first name that comes to my mind. result. On my G&L Tribute L-2000 the E-string was impossible to tune, loads of unpleasamt harmonic components added (and overwhelming) the fundamental tone, as the wound was wrapped starting from a good 1-inch past the bridge saddle. And if the open E-note was impossible to tune, you should've heard what came from playing at 10th, 11th or 12th fret... a Theremin with exhausted batteries and a drunken performer would have been more in-tune. I tossed them in the wastebin: great look, neat feeling, unusable product (unless you have a bass with separate tailpiece and bridge).
