Abstract
An electronic stringed instrument having a first pickup device and a second pickup device. When any one of the strings is picked at a picking position between the first pickup device and the second pickup device, vibrational waves propagate from the picking position toward both sides of the string. When the advancing waves pass the first and second pickup devices, the first and second pickup devices output electrical signals. A time difference between the electrical signals provided by the first and second pickup devices is calculated to determine the picking position. Note tone color and other tonal parameters are controlled based on the picking position.
