Question

with what would you use as a wah wah pedal, bicyle, stock car, electric guitar, baby

Answer 1

A wah-wah pedal is typically used with an electric guitar. It's a guitar effects pedal that alters the tone and frequencies of the sound, creating a distinctive "wah" sound when it is engaged. While the other items listed (bicycle, stock car, baby) aren't typically associated with musical effects or instruments, the electric guitar is the clear choice in this context.
