Sound effects control system for musical instruments

A system for varying the sound signals output from a musical instrument comprising:

• at least one tactile controller constructed from a compressible material and defining a lumen, wherein said at least one tactile controller is compressible through a pre-determined range of physical motion which results in a corresponding change of pressure within said lumen and wherein said at least one tactile controller is configured to be mounted externally in a raised position on a surface of said musical instrument in a location wherein said musician can depress said at least one tactile controller towards said surface to thereby produce a control signal that corresponds to the change of pressure within said lumen of said at least one tactile controller, while simultaneously playing said musical instrument;
• and
• a control box which receives said control signal and also receives an output signal from said musical instrument and, in response to receiving said control signal, modifies said output signal to generate a modified output signal for varying the sound effects of said musical instrument.

A system for varying the sound signals output from a musical instrument comprising:

• means for producing a control signal by depression of said means from a raised position above a first surface towards said first surface of said musical instrument wherein said means includes a lumen and depression of said means towards said first surface results in a change of pressure within said lumen;
• and
• means for modifying an output signal of said musical instrument in response to receiving said control signal.
