Optical Phototransistor and IR LED Pair
The Whammy 5 utilizes an optical interrupter mechanism where a plastic vane moves between an infrared LED and a phototransistor to determine treadle position. Drift occurs when the light intensity fluctuates due to component aging or dust accumulation, causing the output voltage to deviate from the factory-calibrated logic levels. Replacing these discrete sensors restores the accurate voltage-to-pitch mapping required for the DSP to track the foot pedal's movement correctly.
