They say that, "an ounce of prevention is worth a pound of cure." If you've ever had a gig destroyed by someone accidentally stepping on the point where the Leslie cable plugs into the Leslie Speaker, then you should instantly recognize the value of this simple invention of mine. If it hasn't happened to you, it probably will someday, and THEN you'll understand. I sell these life-saving units for just $45, or $50 including shipping. Send me an email from this website and I will hook you up!
