combo |
The most commonly used type of bass guitar amplifier is the combo. One unit contains all of the aforementioned subsystems:
- Preamplifier: also known as input amplifier, often with gain knob. The term "preamp" is often used to describe both the preamplifier and the signal processor. Technically, these are separate parts
- Signal processor
: tone knobs or equalizer, effects, master volume knob
- Additional features may or may not be built in: effects loop
, compressor
, tuner output, DI output
- Power amplifier
- Loudspeaker cabinet
A combo is the least flexible but often most compact, lightweight and cost effective way to amplify a bass guitar. But if you don't like one specific part about it, you have no choice but to replace the whole unit.
