Re: Rg670 wiring help

The YM-50 is not the best, they tend to break, and its connection depends on the plastic that holds it together.

Re: Rg670 wiring help

Thx for the advice. I'll will try out your sugestions. The YM-50 switch is giving me truble as well and I orderd a new one. I just have to wait few days.
Right now the guitar gives me more headache then fun.

Re: Rg670 wiring help

There is a number of things that could be the culprit.
What you explain is probably that the single coil is out of phase with the bridge pickup.
Since it works fine along with the neck pickup, I would assume that you should reverse the wiring on the bridge pickup. If your bridge pickup is wired with red as hot and green to ground, you could try to switch red with black and green with white (dimarzio colours).

Another thing that could be happening is that the magnet poles are out of phase. You have to make sure that the coils always have the opposite magnet pole.
I guess the Jem555 wiring diagram would be the right one for your guitar, but the heavy blues pickup is a 4 conductor single coil, which makes it a humbucker. To make this a single coil, you need to use black as hot, solder red and white together and isolate them, and green to ground. If that makes it phasing, switch green and black.
I have seen several times on jemsite that players don't do this, but the result is hum cancelling in position 2 & 4. If you keep the single coil with red as hot and green to ground your guitar will hum in position 2&4 and will be hum free in pos 3. Not my cup of tea.

Good luck.

Rg670 wiring help

I'm desperate and need help.
I have an 94 rg670 and wanted to change the quantum pickups for some evolution/ heavy blues combo and i never had an HSH guitar wired before.
I tried everything to find an proper wiring diagram explaining every wire. I tryd the standard RG setup but the problem is that in the second bridge/single position the pickups sound weird, very bright and twangy. Every other selection seams to work fine.
Please help.
