I am a newbie on these EMG pickups, and I have an issue with my soloist. The tone and volume a prewired together (see photo). the problem is they need to be further apart. the black wire is not an issue, I can lengthen that easily. Its the green capacator that I am worried about. If I lengthen, what should I use? does it have to be the same length on BOTH sides or can one be longer.
