Abstract: A sound effects device is used with a guitar having an electromagnetic pickup for inducing feedback into an original signal source for creating a unique musical sound. The device comprises a coil winding which is placed on a hand or wrist of a player for maneuvering the hand in proximity to the guitar pickup. In an alternate arrangement, the coil is affixed to a stand and the guitar is maneuvered by the player for placing the guitar pickup close to the coil. The player thus creates new and pleasing sounds by changing relative positions of the guitar and device in proximity to each other thus allowing for an enhanced unrestricted performance.
