Cab

A cab, short for cabinet, is the speaker enclosure that projects the sound from a guitar amplifier. Different cabs shape tone in unique ways depending on their size, construction, and speaker type. In the world of guitar effects and modellers, a cab sim (cabinet simulator) digitally reproduces the sound of various real-world speaker cabinets, letting players achieve authentic amp tones directly through headphones, recording interfaces, or PA systems without needing a physical cab.
