Boss T Wah TW-1
The Boss TW-1 T Wah is a wah pedal that automatically sweeps the filter based on picking dynamics rather than requiring a rocker pedal. Its controls include Sensitivity, which sets how hard the player must pick to trigger the sweep, and a mode switch for selecting between up, down, or alternating sweep directions. The pedal also has a manual mode that allows the user to set a fixed filter position. When triggered, the filter sweeps through a band of frequencies, creating a wah-like effect that responds to attack and decays over time. The TW-1 features a bypass switch and operates with a standard 9-volt power supply.
