A standard mono guitar pickup - with a magnet, pickup poles and coiled wire
The 3Dxy electric guitar pickup system registers string vibration on two axes to offer a rich, surround sound effect called natural stereo
The 3Dxy system is available in bass format too, with pickups for double bass and violin in development
Each string on a 3Dxy guitar has two mini-coil pickup poles pointing at it, these are set at a 90 degree angle to each other down the left and right of the pickup so that string movement on both the horizontal and vertical axes is registered
A mono signal on an oscilloscope is represented as a line, the 3Dxy stereo signal can be seen as a cloud of points or lines

The incredible guitar virtuosity from the likes of Joe Satriani, Eric Johnson and Stanley Jordan all rely on their string-picking proficiency being registered by the instrument's pickups. These vibrations are then transformed into electrical signals and sent off to an amplifier for our listening pleasure. Using such a setup, string movement can only be read on one axis, the horizontal. The 3Dxy pickup system reads each string twice, on both the horizontal and the vertical and is said to result in a rich, surround sound effect called natural stereo.
