What are the differences between a delay pedal and a reverb pedal, and how do they affect the overall sound of a guitar?

A delay pedal repeats the sound of the guitar after a short period of time, creating an echo effect. A reverb pedal adds a sense of space and depth to the sound by simulating the natural reverberation of a room. The delay pedal adds rhythmic patterns and depth to the sound, while the reverb pedal creates a sense of space and ambiance. Together, they can enhance the overall sound of a guitar by adding texture, depth, and atmosphere.
