The Volector Guitar
The Volector Guitar (2009) - volector.com describes a volector as a single joystick that controls two pickup signals' gain at once; a convenient simultaneous dual signal gain control, that serves as both a master volume and a pickup balance selector.
Again, according to volector.com, the device is preferably mounted just below the commonly picked section of the strings between the neck and bridge pickups. In that location, a volector can be used while picking to easily control the two signals (see image below).
What is most interesting about this gestural control element is not only its complimentary interactive capabilities, but also its sheer versatility. Of course, the designer, Nick Nicholes, intended the joystick to control volume and pickup balance levels; however, as Nicholes points out himself, this is just a conceptual design that can be adapted to any electric guitar for the control of two merging signals.
This essentially makes the capabilities of The Volector Guitar endless as the joystick could interchangeably control any two signals/parameters simultaneously. For example, the joystick could control an external device such as a guitar FX pedal that is processing the signal of the guitar or even pass through a voltage to MIDI converter, thus turning the joystick movement in to MIDI data.
