The T stands for “Touch” and the early TW-1’s actually had the text Touch Wah written on them instead of T Wah. The TW-1 was replaced by the AW-2 in 1991. Together with the CS-1, the TW-1 is the only pedal to have a toggle switch. With only 2 controls, the TW-1 is very easy to control. The later autowah pedals have the added versatility of modulation but for the basic wah sound the TW-1 does the job without forcing the user to read the manual.
