The sound of pickups is different. I needed to determine this difference. The word "Dark" can be replaced by another word. You can offer your name in the difference of sound. You will notice the following changes. 1. After replacing magnets, pickups began to sound brighter ( effect of adding Treble). 2. The sound of pickups became dense. 3. The bass sounds very clearly and dense. 4. The output of the gauges was increased. At me on amplifiers it is a difference in turn of the knob of the Master for 7-10 minutes.
