760FS Deep Talkin Bass : oh well

The price is really high and you think about: should I buy them or not? As they are really recommended and often played I bought some.

When you take the strings out of the package you see immediately how smooth they are and there will be no dirt when you slide over the strings.

Well done for this first step. Strung onto the bass, plugged the bass into the amp, what will happen next? The E string sounds dead already and the g strings sounds like you play a Sitar. The effect of the E string seems to be normal as LaBella told me, the effect of the g string is a mistake and LaBella sent a new string. Hmm, great service by LaBella, but not satisfying when you buy a new product of this price.
