text: Keyboard amplifiers also differ from guitar amps and bass amps in that whereas many guitar and bass amplifier companies often sell standalone amplifier units (which contain a preamplifier and power amplifier) for use with one or more separate speaker enclosures, keyboard amplifiers are almost always combination (or "combo") amplifiers, so-named because they combine a preamplifier, power amplifier, full-range speaker, and a horn-loaded tweeter, all in a single wooden speaker cabinet.
