Abstract
For amplified musical instruments such as electric guitars, this method of extending the range of timbre variation available from a 'wah' type of pedal controlled sound modification effect provides musicians with increased flexibility of expression by including within the controlling range of the foot pedal an unmodified 'dry' condition in addition to the variable modified condition with the capability of blending smoothly back and forth between the two conditions.
