Abstract
A musical tone signal forming apparatus includes a pickup which detects vibrations of a string of an electric guitar and produces a string vibration signal. The string vibration signal and the output of a first delay imparting a first delay time are combined in a first combiner. Second and third delays impart second and third delay times to the string vibration signal, respectively. Delayed signals from the second and third delays are combined in a second combiner. Outputs of the first and second combiners are combined in a third combiner. The first delay time is determined by the distance between a bridge and a first imaginary pickup supposed to detect vibrations of the string. The second delay time is determined by the distance between the first imaginary pickup and a second imaginary pickup supposed to be disposed nearer to the bridge. The third delay time is determined by the distance between the bridge and the mid-point of the first and second imaginary pickups.
