More info: The [[Guitar Resonator]] allows a musician to generate feedback while playing normally with both hands. Effects units are electronic devices that alter how a musical instrument or other audio source sounds. Some effects subtly “color” a sound, while others transform it dramatically. Effects can be used during live performances (typically with electric guitar, keyboard, or bass) or in the studio. While most frequently used with electric or electronic instruments, effects can also be used with acoustic instruments and drums. Examples of common effects units include wah-wah pedals, fuzzboxes, and reverb units.
