Feedbackbass
The Feedbackbass is a modified E-bass guitar. It is played with two monitors, which are connected to an amplifier, that is also connected to the BassGuitarDevice. If the strings produce sound the monitors will diplay it, but the vibration also let the strings swing harder. Therefore a kind of "physical" feedback is produced. Like with a theremin you can change the sound by moving the monitors far or close to the guitar.
