The bridge humbucker on my Jackson DK-2 has suffered from a significant loss of volume and gain. The neck single coil has more gain and volume.

What could the problem be?

my guitar had the exact same problem.

the problem on mine was the pickup selector switch. i took my guitar to the luthier and they replaced it and now it works fine.
