The Rocksmith guitar that comes with the deluxe version of the game is a Les Paul that has a single humbucker pickup.
A humbucker is a type of electric guitar pickup that uses two coils. Humbuckers have higher output than a single coil pickup since both coils are connected in series. Like a single coil pickup, the magnets in a humbucker produce a magnetic field around the strings, which in turn induces an electrical current in the coils as the strings vibrate. A humbucking pickup is essentially two single coil pickups, one of which has the north poles of its pole pieces oriented toward the strings, and the other has the south pole of its pole pieces oriented toward the strings. Since the coils are connected in series and out of phase, noise and interference are significantly reduced. Humbuckers get their name because they cancel out interference and "buck the hum" induced by alternating current from power lines and other devices, which is normally experienced with single coil pickups.
I've read people having trouble with the game picking up notes on their guitar.
Could this have anything to do with the pickup? Does the game detect notes better if your guitar is equipped with a humbucker ?
Best Answer
In my experience Rocksmith does benefit from a humbucker. This is simply due to the reason mentioned in joshbuhler's answer - the more volume, the better. Since the average humbucker has a higher output than the average single coil, it works a bit better. Another thing I've noticed is that Rocksmith works better with a brighter pickup. For instance, on an LP-type guitar the bridge pickup seems to work better. When using the neck pickup, Rocksmith tends to have problems with detecting notes on the higher strings, especially when playing chords, even with the volume and tone knobs cranked.
So my order of preference for pickups to use with Rocksmith, all other things being equal, would be:
Everything depends on the actual guitar and pickups, though. Neck humbucker on a bright-sounding guitar might be better than the bridge humbucker on a Les Paul, and high-output single coils (like P90s) might be better than any humbucker. I'm currently playing Rocksmith with a telecaster that has a 10k single coil in the bridge, and it works like a charm. Even better if I switch the neck pickup in series with it.
In the end, you just have to experiment with your guitar(s) and pickups and see which combo works best for you.
One thing to try if you just cannot get Rocksmith to detect notes properly with your guitar, would be to put a booster or compressor pedal between the guitar and the Real Tone cable. I know the game warns you not to do that, but I don't see the harm in putting something there that can help bring the levels up a bit. At least theoretically. I might try it out later and see what happens.
