Abstract:
1. Device for automatic tuning of a string instrument, in particular, a guitar, comprising: a) a detection device detecting a tone generated when a string is struck and outputting a digital signal corresponding to the detected tone, b) a memory device storing preset digital signals, which correspond to a desired tone, c) a comparison device comparing the digital signal output by the detection device with a digital signal stored in the memory device and corresponding to the desired tone, d) an adjustment device changing the tension of one or more strings, e) one or more drives driving the adjustment device, and f) a controller connected to the comparison device and controlling the one or more drives via a bus line transmitting control signals with reference to a deviation determined in the comparison device between the signals representing the generated tone and the desired tone, wherein the controller and the one or more drives are arranged in the string instrument on opposite ends of one or more of the strings viewed in the longitudinal direction of the strings, and wherein the bus line between the controller and the one or more drives includes at least one of the group consisting of a string made from a conductive material, a string coated with a conductive material and a string wound with a conductive material.
