Wah Wah to Write Protect

Wah Wah (Wah)
A changing filter giving more and less filtering of harmonics of an instrument’s sound.

Watt
1) Unit of electrical power.
2) Unit of electrical power derived from the current (or “quantity” of electricity) multiplied by the voltage (or “pressure” at which the current is delivered). Stage lighting equipment is rated in Watts (or Kilowatts – 1 kW being equal to 1000W). This refers to the amount of power required to light the lamp.
