    I have installed the J99 And HB pickups with Active circuit into my Basskit. I followed all the instructions. But something wrong with the sound. If I turned both pickups on, the output is very low, and the low frequency is attenuated. No matter if the humbucker pickup set into humbucker mode or single coil mode.

    I can’t find any instruction related to connecting HB pickups with active circuit, I know HB has black wire hot output, while J99 has red wire hot output. So, I soldered the HB pickup black wire to active circuit with B (black) sign, while the red and the white wires soldered to coil switch, and the green and shield wires soldered to active circuit with S sign (shield) and to ground.
    So, I didn’t soldered any wire to R sign (red) in active circuit. Is that the correct way or not ?? Could it be the problem that caused the low output when both pickups turn on ???

  2. Maybe you have wired the pickups out of phase with each other. That's what the symptoms sound like to me, though I could be wrong.

    To really get the answer, you should contact Carvin directly. Go to, and look for a link to returns & repairs.
