Other Pedals and Rackmount Units
Not all stompboxes and rackmounts are effects. Strobe tuner pedals indicate whether a guitar string is too sharp or flat. A footswitch pedal such as the "A/B" pedal route a guitar signal to an amplifier or enable a performer to switch between two guitars. Guitar amplifiers and electronic keyboards may have switch pedals for turning built-in effects on and off. Some musicians who use rackmounted effects or laptops employ a MIDI controller pedalboard or armband remote controls to trigger sound samples, switch between different effects or control effect settings.

Famous quotes containing the word units:
“Even in harmonious families there is this double life: the group life, which is the one we can observe in our neighbour’s household, and, underneath, another—secret and passionate and intense—which is the real life that stamps the faces and gives character to the voices of our friends. Always in his mind each member of these social units is escaping, running away, trying to break the net which circumstances and his own affections have woven about him.”
—Willa Cather (1873–1947)
