That's what I got going on with my 1988 Yamaha rgx612a, just one emg-81 and a volume pot, the other two single coil pickups are not connected to anything, they were stock actives. That's my favorite guitar.
You think this would be a good idea with a Seymour Duncan Distortion, or would that make it too bright? It's in a Ibanez LP copy. Or how about a JB?
