I bought a bass at Christmas. I just noticed that in the specs, I am supposed to have a Q-Tec Super P pickup and a Q-Tec Super J in my bass. However, my pickups simply have EMC on the P, and my J is unbranded. Are these good pickups? Are they better or worse than the Q-Tec? Should I upgrade(my J, my P is really phat, but my J is too tinny, especially with full treble. Is this because its my bridge pickup, and the strings are tighter over it?)? Anyway, please reply, this i really bugging me.
