I just install new set of Delano pickups in my warwick state 2 in passive and Vol-Bal-Tone configuration. I like the tone of it but output of the bass noticeably decrease. With Delano pickup the output is very low. I used to turn both gain and volume knob in my amp at 10-10.30 but right now I have them at 12.00 to get same sound level. After I play around for a while, I just notice that the output increase a bit when I turn the balance all the way up or down using only neck or bridge pickup. This quite strange to me, in Vol-Vol-tone common Jazz bass configuration which I get used to, the maximum output can be get from turning both volume all the way up. Is this common thing for balance pot?
