I just installed 3 livewire pickups (H-S-S) in my Jackson SL-1 (1 vol, 1 tone). I have 3 questions:

1. The hiss noise of neck and middle single coils lirewire is very high, and the noise become almost not acceptable when turn on the OD/DS effect. How can I reduce the nosie?

2. The Metal livewire (bridge) pickup is so powerful and high output, so there is a big volume gap between I switch to the middle or neck pickups from the bridge. Is it normal? Should I install the 100K ohm resistor? (The schematics just said it's "optional", please tell me "yes" or "no", thanks!)

3. What is the capacitor value? It's 0.047u or 0.1u? And what's the difference?

Thanks!!
